High speed RPM's

Recommended Posts

I bought my bike slightly used (2,2XX miles) and the previous owner put on some aftermarket parts. TwoBros exhaust, PC5, higher flow filter, etc. My question, is what RPM are people running in 6th at 70mph? I'm trying to determine if he changed any of the sprockets (I figured it was a viable possibility with all the other aftermarket changes he made) because I'm running 5-5400rpm at 70 in 6th gear and it just seems slightly high to me..

Not 100% sure (been a while since I paid attention) but that sounds about right. You could just count the teeth. Stock is 16 front, 43 rear.

Yeah, that sounds stock, but counting the teeth will be your most accurate move. I am still in the <600mi break-in period, so "no sustained rpm over 5,000" is brutal.

Thanks for the reassurance and the suggestion, I'll take a look when I get a chance and see what the tooth count is.

That is about the same for mine in 6th going 70 and it's completely stock.  I don't think it's high when you consider redline is 10k.
