‘Re­flash the ig­ni­tion on newer mod­els and 200mph is in reach’

Motorcycle News (UK) - - BUYING & SELLING -

When he’s not sell­ing Hayabusas, Mike is go­ing ex­tremely quickly on them; he set a Euro­pean land­speed record aboard his own turbo Busa, av­er­ag­ing 229mph in a two-way timed run at Elv­ing­ton in 2012.

“The Hayabusa re­mains Suzuki’s flag­ship ma­chine; it’s unique in terms of its mix of styling, earth-shat­ter­ing per­for­mance, us­abil­ity and prac­ti­cal­ity. It’ll match and beat many of the lat­est top su­per­bikes in the ac­cel­er­a­tion stakes, while still prov­ing com­fort­able enough to zip through Europe, and they’re now cheap enough to prove tempt­ingly af­ford­able. Just as im­por­tant, they are re­li­able too.

“Ow­ing to their shorter stroke en­gine, the orig­i­nal 1299cc mod­els are slightly smoother than the GEN II 1340cc bikes, which fea­ture float­ing mounts on the fuel tank to damp out some vi­bra­tions.

“That said, the re­vi­sions to the pis­tons, valve train, ex­haust and the in­clu­sion of Suzuki’s Dual Throt­tle Valve sys­tem make the post-2008 GEN II vastly su­pe­rior in terms of power de­liv­ery and re­sponse; it’s much more free-revving and also ben­e­fits from hav­ing slightly more torque at a lower rpm, and also a 17bhp boost in peak power, up from 155bhp to 172bhp.

“The welds on the alu­minium sub­frame of early mod­els known to crack when fully loaded with lug­gage, af­ter­mar­ket ex­haust sys­tems were thought to be the cause. There was never an of­fi­cial re­call but some own­ers were given new sub­frames out of cour­tesy. 2001 on­wards mod­els had stronger, steel sub­frames.

“Speed demons can free the Busa by re­mov­ing the elec­tronic re­stric­tions. For 2001-2007 mod­els, a TRE Tim­ing Re­tar­da­tion Elim­i­na­tor is fit­ted into the bike’s wiring loom and works by trick­ing the bike into think­ing it’s in fifth gear all the time – the gear that has the best ig­ni­tion curve for all-round driv­abil­ity. As the bike thinks it’s in fifth gear, the sixth gear rev limit never kicks in so al­lows for a greater top speed. Later mod­els can have their ECU re­flashed by a spe­cial­ist in or­der to re­move the re­stric­tions – these bikes are then eas­ily ca­pa­ble of 200mph with noth­ing more than an af­ter­mar­ket ex­haust sys­tem and smaller rear sprocket.”
