08 Hyperbusa Tech Notes
FYI ? 08 Hyperbusa tech notes ? From Sport Rider Magazine Aug 2007 Edition
Target 190 bhp
More compact cylinder head w/titanium valves same size as before (33mm intakes, 27.5mm exhausts) ? single valve spring ? Hydraulic cam-chain tensioner ? Lighter pistons w/smaller pin diameter (18mm vs 20mm) running with 2mm more stroke (81.0 x 65.00mm vs 81.0 x 63.0mm) ? SCEM coated cylinders for 1340cc displacement (42cc more than before) ? Compression 12.5:1 vs 11.0:1 ? Rings ion-plated ? con_rods holding pistons are now shotpeened chromoly steel ? Stronger crank w/heavier duty clutch and transmission filled with heat treated, shotpeened cogs ? Final drive gear 43/18 ? Revised cylinder ventilation reduces pumping losses - Gear driven counterbalancer and back torque limited clutch (same as old) ? Smaller throttle bodies with 44mm GSXR1000 type injectors & air cleaner ? Redesigned exhaust 4-into-2-into-1-into-2 triangular GSXR1000 type duals ? More curve on radiator, larger oil cooler & dual cooling fans ? SDMS system allows rider to choose three different power levels - Frame is a carry over ? Center stand removed ? Wheelbase 58.5in ? Rake & trail are 24.2deg/3.85in ? Seat height 31.7in ? Dry weight 490lbs ? Fully fueled 555lbs ? Better brakes & rotors
SRM writer caught a glimpse of the dyno monitor and it looked like it began with a ?2?. Busa expected to make at least 175 ponies, and likely more. Suzuki is not saying how much horsepower for U.S.
