So far I've seen 175 on my Speedo while doing a 6th gear pull testing the clutch. But I know it's off from the tire size change(190\50 from a 200\50) so was probably 168-170. Track times so far 10.85 @ 135 going thru traps in 3rd gear. Mods so far are full muzzy exhaust,k&n air filter, 8" swing arm extension blocks, led lights all around. Mods to come pc5, sprocket change front 17 rear 50 new chain, billet clutch basket. 2001 Zx12r
I did an instrumented top speed half-mile event and it did 189 mph in a standing half mile, backed up with three more runs over 180. Bike was stock height, with a tune and -1 gearing on the back sprocket. It absolutely would make 200 with an unlimited run. It's also a nine second bike at 148, stock length, at the dragstrip.
