^ Idk what bike you are riding but you should check one more time. If you are riding this bike in 3rd gear all the way to 60, you are doing some serious damage.Not sure completely since I've never taken specific note of it, but 2nd seems to go to about 35-40, and 3rd about 60. That's all I've noted specifically.
If you look at the graph attached to this post... (see below) ...you will see the true ( rather than indicated ) speed in each gear. It is not difficult to reach 10,000 in the lower gears but top gear will only pull to around peak power, which is 8,500 r.p.m.
