I got on a nice straightaway with the wind to my back and rocked to 150KPH tapped out at 11000+ [was more worried about some jerk pulling out in front of me] I am very happy with the bikes performance with the V-force, Tyga and 34mm carb. I want to do a fuel mileage check, but with the whether its going to be a bit difficult but I should be able to get a good ballpark figure. Just need to keep out of the throttle for a tankfull now!

you should be seeing more speed with your set up. You should at least get 100mph!!

why'd you change to a 16 tooth front sproket? i get about 170-175 kph on the dash out of 17-40 but its probly more like 150 real speed!

if thats you speed then your bike is pretty slow.

my rs with 15-40 used to top out at 95mph (155kph)

I didnt like to have to flail the clutch every time I took off. Its all hills here where I live and it just went against my grain to abuse a clutch like that. Its a dream to take off now.
Seems some bikes go better than others. I have watched vids on youtube where guys get 170+ and rev to 13000. Ha good luck. Mine falls flat on its face after 11000.

what approx 0-100 kph are you guys getting?

mods make zero differnce to speed rather acceleration at which it gets there. If I can did it up and find it i made an excel spreed sheet some time ago to work out all the speeds and against revs and sprocket ratios. From memory, 15:40 sprockets will see the bike doing approx 145kms/hr at 10,500rpm. I can only suggest the guys claiming to have used the same gearing and getting higher figures must be reving higher.
I would love to know what sort of times as well.

Anyone ran their bike and got a 0-100 or 0-400m?
