Top end speed!!

[Phillip]

I want to know everything to get my bike about 85- 90 mph.
I know HRC kit, full pipe, filter, sprockets, vortec cdi, what else??

Taller tires?

Just get a car so you dont kill youself lol j/p man idk wat else

[lukester720]

sprockets alone could get you there, and taller tires in the rear.

A 36t rear sprocket and 22' tires would put you about 90.

If you got a new cdi that would let you rev 10500 then with the 36t rear and 22' tires you could theoratically go 100 mph. Personally I don't think this bike has enough power to do it but I may be wrong.

get on bluetraxx and do the sprocket calculator....Ive got my 416 geared to go around 85 with GPS

i know you can't trust the magazines with anything. but i would think that they would be in the neighborhood of 85-90 if they said it topped out just over 90.

A 14/38 with 22' should be able to get to 84-85. 90 is not out of the question with a 15t front & 22' tires but you won't be able to fit it without removing the case saver and it would be a very tight fit.
