Hey, just wanted to check to see if my bike is pulling the same revs as everyone else's CBR. ok,
4th gear 50kph = 6,000rpm
6th gear 100kph = 9,000rpm
6th gear 160kph = 14,000rpm

5th gear is 1,000rpm to 10kph (eg 100kph = 10,000rpm, 90kph = 9,000rpm etc.)

Please give me feed back to see if they are all the same amongst different models.

P.S my cibby is a 91 RR MC 22

Depends on your sprockets. Sounds almost the same as mine except for 6th, at 110km im sitting on 10krpm 120=11k 130=12k etc etc, lower down it matches closer to yours, so i guess we got different gearing, UNLESS, wait a sec, how much you weigh... I mean.. WHAT!? you did 160km? sorry officer, i won't do it again officer :Police:

A bit OT - but - HDTBoy - what oil do you recommend??

And what Fork oil do you have?

I use Castrol Active 4T from supercheap cause I'm a tightarse. And I've got 10 weight fork oil in it (shell) just changing the fork oil makes a big difference and it's real easy to do
