Could anybbody tell me what my top speed would be with 195/40/14 and a 3:92 diff on an r1.

Cheers des

i would guess you would be lucky to see just over the ton esp on 14's with low profiles on

on a 3.92 with 195-50-15s my blade bec did 110 flat out. chnged it to a 3.62 lsd to get 125mph

Don't think anybody makes that tyre size. 50 profile is probably the lowest you could find on a 14" rim.

Just put those options in Quaife gearcalc and if there was such a tyre size you would be doing 95mph at 11k rpm in 6th

a 98 R1 with a 3.92 diff and 195/50/15 is 110. On 14s that would be about 106 MPH. 2004 R1s have more revs so that would be a bit higher.
