Tricky course conditions at the legendary Bonneville Salt Flats have once again proved challenging during the latest stage of the Triumph Motorcycles Land Speed Record attempt.  With clear sun and virtually no wind, rider Guy Martin set off from mile marker 9 to record his FIM-required certification run.

    Setting off smoothly, Guy was making good power in mile one when the Triumph Infor Rocket Streamliner lost traction on a damp section of the salt surface, causing the rear of the machine to step out of line and the streamliner to go down on the course. Guy was completely uninjured in the incident, however the streamliner will now require a full inspection before any further runs can take place.

    “It’s one of the challenges of Land speed racing - the salt surface can be so unpredictable. We’ll fully inspect the streamliner and get ready for the next phase of our attempt” commented Triumph Infor Rocket Streamliner designer Matt Markstaller.

    Rider Guy Martin added “It’s all part the job boy, isn’t it? Feeling our way. I guess if it was an easy thing to do everyone would have done it by now.  So we’ll get a plan sorted and get on with the next go at it as soon as we get the chance.”


    TT Legend Guy Martin and the Triumph Motorcycles Land Speed team have spent today making final preparations for the next stage of their Land Speed Record attempt at the Bonneville Salt Flats. Plans for the day included the required FIM certification pass at 300mph.

    However, on heading up to the start of the course, with the streamliner under tow the Triumph Infor Rocket Streamliner passed over a rut in the track at the two mile marker.The rut and the soft surface caused the Streamliner to fall onto its side. Guy sustained no injuries and the machine was undamaged bar a number of minor scuffs to the body.

    The team were quick to bring the Streamliner back to the pit area to carry out an assessment and begin preparations to run again. Shortly after course officials informed the team that the course was to be closed for the evening for all motorcycles due to the conditions.

    The team will now continue to prepare the Streamliner to run tomorrow. Both the team and Guy look forward to returning to the salt flats to continue the next stage of the Land Speed Record challenge in the morning.


    The sun is out at Bonneville this morning and the Triumph Motorcycles Land Speed team are well into preparations for today’s attempt to set a new motorcycle land speed record.

    The team arrived this morning to beautiful sunny conditions and much improved track conditions. A number of the car competitors have already undertaken their first passes of the day and the team has confirmed that the Triumph Infor Rocket Streamliner will carry out its first run of the day at 11:30am.

    “Spirits within the team are very high today and everyone is looking forward to getting our Land Speed Record attempt underway this morning.” comments Matt Markstaller, Crew Chief and Triumph Infor Rocket Streamliner designer.


    Following this morning’s update, and after a further course inspection, Triumph Motorcycles, the company behind the 2016 motorcycle land speed record attempt at Bonneville, has confirmed that it has postponed running for today due to the course conditions.

    While the track conditions continue to improve, this afternoon’s course inspection showed that there are still areas at the upper limits of the eleven mile salt flat course that are still too wet to safely undertake any runs at present.

    Regular course inspections will continue to be conducted by the team throughout the rest of the afternoon and preparations have begun to ready everything for tomorrow’s scheduled runs.

    “To perform at this level we need the optimum conditions – and today we didn’t quite have the course conditions we needed. We will be back on the salt tomorrow morning ready to go and we’re looking forward to getting underway with our record attempt” comments Matt Markstaller, Crew Chief and Triumph Infor Rocket Streamliner designer.


    Triumph Motorcycles, the company behind the 2016 motorcycle land speed record attempt at Bonneville, has confirmed that its bid to regain the title has been delayed due to course conditions. There will be a further update early afternoon.  

    A series of rain storms, at Bonneville, at the start of this week, 13 – 16 September, 2016, has meant that the eleven mile salt flat course is still too wet at the upper limits of the course to safely undertake any runs at present. However the weather conditions are now good and the track conditions are improving hour by hour.

    The Story so far….


    With over 20,000 man hours and four years of development the Triumph Infor Rocket Streamliner has seen Matt Markstaller, the man behind Triumph’s imminent land speed record bid, and his team turn what started as a brief conversation in a wind tunnel, into a 400mph Land Speed Record challenger.

    Where did it all begin

    How do you go about designing a 400mph motorcycle

    Constructing the world’s fastest motorcycle

    Where do you go to test a 400 mph Streamliner

    Sixty years since Triumph Motorcycles became the World’s Fastest Motorcycle Manufacturer

    What’s been happening while we have been away from the salt?


    The last few weeks have seen the team begin final preparations for the Land Speed Record attempt, following its successful practice runs at Bonneville at the beginning of August. The practice week saw TT Legend Guy Martin get acquainted with the Triumph Infor Rocket Streamliner on the salt for the first time. Throughout the week, Guy and the Streamliner performed excellently and the test week came to an end with Guy setting a new Triumph record of 274.1 MPH, to become the fastest ever Triumph Motorcycle.

    Pleased with the week’s work, Matt Markstaller, lead designer and crew chief of the Triumph Infor Rocket Streamliner, and his team, undertook the sixteen hour trip home from Bonneville to the team’s base in Portland, Oregon to begin final preparations.

    Even though the Streamliner had only covered approximately 20 miles on the salt during the week, the first job that faced the team was the mammoth task of cleaning the entire vehicle. This is a very time consuming task, that takes the team an entire week to complete. During this time the Streamliner is cleaned up to four times, to remove the salt collected during each high speed run where it forces its way into each and every component.

    Following the mammoth job of cleaning the Streamliner, the next task that faced the team was to begin removing and inspecting the major components. This process saw the team remove the engines to conduct a series of visual and mechanical checks.

    During the engine inspection, the oil and filters are changed and a visual check is conducted for any wear or visible signs of stress points on both engines. With this complete, the engines were sent to the dyno to carry out a series of power simulations to re-check each unit’s performance and make sure everything is OK with the motors.

    While the engines have been on the dyno, the rest of the team inspected the monocoque, suspension and drive train components. Each part has to be meticulously checked for any signs of wear or stress and then serviced and lubricated, before being refitted to the Streamliner.

    The time back at their base in Portland was also used to change the specialist Goodyear Land Speed tyres. While normally a simple process on a road motorcycle, the process on the streamline involves 200 screws being removed and the wheel stripped, down before the tyre can be changed. The whole process is then reversed and, before both wheels are refitted to the bike, they are sent away to be checked to ensure they are balanced correctly and are structurally sound.

    Due to the high speed the tyres need specialist preparation and testing. To do this, the team has to send the wheels and tyres to a specialist testing facility. This facility, is the only place in the USA that can undertake testing over 400 MPH and underload to ensure can cope with the stresses placed on them during the record runs.

    With just a week remaining before heading back to salt final components are being refitted, the trailer is being packed and the Triumph Infor Rocket Streamliner is being loaded for the 16 hour return journey to the salt.


    En continuité avec les essais réussis du mois d’août sur le lac salé de Bonneville, qui ont permis d’atteindre la vitesse de 274.2 mph (441,2 km/h) et de devenir la Triumph la plus rapide de l’histoire, Triumph Motorcycles confirme que les tentatives de battre le record absolu de vitesse à moto se dérouleront mi-septembre si la météo le permet.

    Piloté par la star du TT, Guy Martin, le  Streamliner Triumph Infor Rocket retournera sur le lac salé de Bonneville et tentera de battre l’actuel record de 376.8mph (606,27 km/h) sur la ligne droite de 11 miles (près de 17km). Bien que les conditions étaient bonnes pour les essais, le team a vu que le sel en surface n’était pas complètement capable de supporter la vitesse de pointe du Streamliner. En concertation avec le responsable des records de la FIM Mike Cook, le team a décidé que les dates sur septembre seront la meilleure opportunité possible pour les conditions de course requises pour battre le record.

    La semaine d’essais qui s’est terminée avec le run à 274.2 mph (441,2 km/h) le mardi 9 aout a prouvé que le Streamliner Triumph Infor Rocket et son pilote Guy Martin étaient prêts. Toute cette semaine, Guy Martin a impressionné tout le monde par sa rapidité et sa capacité à maitriser aussi rapidement les 1000 CV du Triumph Infor Rocket Streamliner sur le lac salé et d’atteindre tous les objectifs fixés par le manager de l’équipe et par le designer du Triumph Infor Rocket Streamliner Matt Markstaller.  

    Sur le retour en Septembre sur le lac sale, Markstaller dit: “Nous sommes là où nous souhaitions être à la fin de notre semaine d’essais à Bonneville et nous sommes prêts à lancer nos tentatives pour battre le record. Guy nous a tous impressionné par la manière à laquelle il s’est approprié le streamliner et son pilotage sur le sel.

    “Bien que les conditions étaient parmi les meilleures que j’ai connues ces dernières années, nous pensons qu’elles peuvent encore s’améliorer. Pour cette chasse au record sur deux roues, les conditions doivent être le meilleur possible pour nous permettre de mettre toutes les chances de notre côté pour battre ce record. Nous pensons qu’attendre quelques semaines de plus vous nous permettre d’avoir de meilleures conditions et vont nous mettre dans une position idéale pour battre ce record. ”


    Triumph Motorcycles held the title of “World’s Fastest Motorcycle” from 1955 to 1970 with the exception of a brief 33-day period. The Triumph streamliners to carry world records were the Devil’s Arrow, Texas Cee-gar, Dudek Streamliner and Gyronaut X1, the last being at 245.60 mph (395.28 km/h). Today's bar now sits at 376.363 mph (605.697 km/h).

    Now Triumph has teamed up with Matt Markstaller and Bob Carpenter and pulled together a team to restore Triumph Motorcycles’ legacy in land speed racing. Markstaller serves as aerodynamic engineer; Carpenter is the high-peformance engine builder; Riding the purpose-built Triumph Infor Rocket Streamliner over the measured mile will be Isle of Man TT racer and multiple speed record holder Guy Martin. This multi-national team converges on the Bonneville Salt Flats, a 40 square mile salt pan in northwestern Utah, with the goal of a 400 mph plus record-breaking run.

    The Triumph infor Rocket features Carbon Kevlar monocoque construction with two turbocharged Triumph Rocket III engines producing a combined 1,000+ HP. It is 25.5’ long, 2’ wide and 3’ tall, a true rocket on two wheels powered by methanol fuel, the bike is competing in the Division C (streamlined motorcycle) category.



    Le pilote de TT Guy Martin a poussé le Triumph  Infor Rocket Streamliner lors des tests à une vitesse de 274.2 mph (441,18km/h) sur le lac salé de  Bonneville. Le Streamliner est devenu à cette occasion la Triumph la plus rapide de l’histoire.

    Le 8 Août 2016 devient une date importante de notre histoire et dans notre course au record du monde. Le pilote de TT Guy Martin a poussé le Triumph  Infor Rocket Streamliner lors des tests à une vitesse de 274.2 mph (441,18km/h) sur le lac salé de  Bonneville. Le Streamliner est devenu à cette occasion la Triumph la plus rapide de l’histoire, en battant le précédent record officiel de 245,667 mph (395KM/h), ainsi que le record non officiel de 264mph (424,78km/h) établi par Bob Leppan sur le Gyronaut X-1.

    Les conditions étaient proches du parfait en ce dernier jour de test. En confiance après plusieurs jours de tests et de runs validant les éléments menant au record, le team s’était fixé comme objectif de battre le record de vitesse Triumph. 

    Juste après 8:30, Guy Martin et l’équipe était prête pour un premier run. Après un départ parfait, Martin accéléra le Streamliner jusqu’à 274.2 mph (441,18km/h), écrivant un nouvelle page de la fabuleuse histoire de notre marque. Juste après la marque des 2 miles, Martin effectua un stop parfaitement maitrisé pour venir se poser près du camp de base ou il apprit qu’il venait de battre le record de vitesse Triumph qui datait de 46 ans.

    Ce run du record du 8 Août montre la confiance de Guy Martin et de l’équipe sur le lac Salé de Bonneville pour la tentative du record absolu de vitesse à deux roues. Toute cette semaine, Guy Martin a impressionné tout le monde par sa rapidité à maitriser le Triumph Infor Rocket Streamliner sur le lac salé. A chaque fois que Martin a piloté le streamliner, il a été capable d’atteindre tous les objectifs fixés par le manager de l’équiper et par le designer du Triumph Infor Rocket Streamliner Matt Markstaller.

    Lorsque nous avons demandé à  Guy Martin ce que cela faisait d’être le détenteur du record de vitesse Triumph, il nous a répondu: “C’est bien et on va dans la bonne direction. Mais c’est juste un pas de plus pour atteindre ce que l’équipe et moi nous nous sommes fixes. »

    Le Triumph Infor Rocket  a un châssis en carbone Kevlar monocoque et est propulsé par deux moteurs de Triumph Rocket III turbocompressés produisant 1000 CV à 9000 tr/mn. La moto fait 8m de long, 60 cm de large et 1m de haut.

    Alimenté par du méthanol, la moto concourt dans la catégorie C (streamlined motorcycle). 

    Le record de vitesse et Triumph ont une longue histoire commune. Triumph a conservé le record du monde de vitesse à moto de 1955 à 1970*. Les Streamliners Triumph ayant battu le record du monde sont: le Devil's Arrow, le Texas Cee-gar, le  Dudek Streamliner et le  Gyronaut X1, ce dernier ayant atteint 245.667 mph (395.28 km/h). Le record actuel est détenu par depuis 2010 par Rocky Robinson sur le streamliner  Ack Attack  et est de 376.363 mph (605.697 km/h).

    Le nom des légendaire Bonneville vient du record du monde de Johnny Allen en Septembre 1956 sur le lac sale de Bonneville avec une vitesse de  193.72 mph (311,7 km/h). Le premier modèle de T120 Bonneville fut présenté au salon moto de Earls Court et fut disponible en 1959.


    From 1955 to 1970, a Triumph powered streamliner held the absolute motorcycle land speed world record.

    That legend began in 1954 at Pete Dalio’s Triumph shop in Dallas (operating today as Big 'D' Cycles). On a Saturday afternoon shortly after closing, legendary Triumph mechanic and tuner Jack Wilson recalls, when “Pete, myself and Stormy Mangham were sitting around talking about how Wilhelm Herz had raised the record to 180 mph on an NSU.”

    That brief conversation set in motion the events that would forever alter motorcycle history. 



    Title partner for Triumph’s 2016 record attempt will be global cloud applications provider Infor with further support from iconic clothing brand Belstaff.
