After a year’s de­lay, Tri­umph Stream­liner record bid launches at Bon­neville Salt Flats

Motorcycle News (UK) - - This Week -

Guy Mart­inõs as­sault on the mo­tor­cy­cle land speed record has blasted off on the Bon­neville Salt Flats with a week of shake­down test­ing. Lin­colnshireõs finest wrig­gled down into the cock­pit of the 1000bhp Tri­umph In­for Rocket Stream­liner to com­mence a se­ries of tests ahead of the of­fi­cial speed record at­tempts sched­uled to take place later this month.

Once the base camp had been set up, the team be­gan sur­vey­ing the 11-mile salt course, and reac­quaint­ing Guy with the Rocket Stream­liner. Crew Chief and de­signer Matt Mark­staller spent some time get­ting Guy up to speed with the con­trols and con­struc­tion of the Stream­liner, before Motec en­gi­neers joined in to talk through the dig­i­tal dash dis­play as well as dis­cussing the Stream­lin­erõs throt­tle re­sponse and be­spoke en­gine and steer­ing con­trols.

Guy then met the rest of the team to dis­cuss the …hlins sus­pen­sion set­tings and to sort out his seat­ing po­si­tion within the cock­pit. Once ev­ery­thing was sorted the team were able to let Guy start to get to grips with the Stream­liner on the salt dur­ing lowspeed tow­ing runs, giv­ing Guy the op­por­tu­nity to feel the Stream­liner in mo­tion, and prac­tise his con­trol in­puts.

The next stage of the after­noon in­volved a se­ries of brak­ing and con­trol ex­er­cises to help Guy get to grips with the Stream­liner at lower speed Ð which did­nõt ap­pear to cause him any is­sues. ÒITÕS all go­ing ac­cord­ing to plan,ó said Guy after the first ses­sion.

By the close of day one prepa­ra­tions be­gan to start the two 2294cc Tri­umph Rocket III en­gines that power the Stream­liner Ð de­vel­op­ing a com­bined 1000bhp @ 9000rpm. The sound of the en­gines echoed around the salt flats while the team ran a num­ber of sys­tem checks. Un­for­tu­nately an undis­closed me­chan­i­cal is­sue post­poned the first pow­ered run on the morn­ing of day two, and the team had to tow the Stream­liner back to the pits to fix the prob­lem.

But on the dawn of day three sun­rise sig­nalled per­fect con­di­tions, and with the Rocket ready for ac­tion again the team towed Guy up the salt for an ori­en­ta­tion run, before rip­ping the air asun­der with the sound of the 1000bhp twin Rocket en­gines.

And, at just past the seven-mile marker, Guy gen­tly eased the Rocket away un­der its own power for the first time, with an agreed tar­get of hit­ting 80mph before slow­ing to a con­trolled stop back at the pits. After three miles Guy was trav­el­ling at a steady 95mph before throt­tling off at the two-mile marker and com­ing to a con­trolled stop at the base camp, with Guy ap­par­ently con­firm­ing that it felt Òspot on.ó

Guy and the team are on sched­ule with the test pro­gramme so far, al­though high winds put an end to ac­tion on day three of the test. But the weather im­proved on day four, and as MCN went to press test­ing was un­der­way again, with the fore­cast for the rest of the week look­ing favourable.

Tri­umph have a strong his­tory of break­ing the land speed record, with pre­vi­ous record-break­ers in­clud­ing: Devilõs Ar­row, Texas Cee-gar, Dudek Stream­liner and Gy­ro­naut X1 Ðthe for­mer achiev­ing a top speed of 245.667mph (395.28kph). The cur­rent record has been held by Rocky Robin­son since 2010 rid­ing the Top Oil Ack At­tack stream­liner, at 376.363mph (605.667kph). The team is tar­get­ing the record for the Di­vi­sion C (stream­lined mo­tor­cy­cle) cat­e­gory, and thereõs no doubt that theyõll want to set a sig­nif­i­cant new record when the bid takes place at the end of Au­gust.

The en­tire record bid is be­ing filmed by Chan­nel 4 as a con­tin­u­a­tion of the mas­sively pop­u­lar Speed with Guy Martin se­ries, and will air shortly after the record bid.
