[QUOTE="Mihylo33, post: 223845, member: 408"] An exaggeration of sorts. Peak power is at 12,000rpm and varies from bike to bike at that cc range with a max rpm of about 14000. 65cc and 125cc 2stroke bikes spool up at right around the same rpm range with 250cc 2 strokes having a max rpm of about 10,500-11k and making peak power right around 9,000rpm. I have heard that procircuit 125national motors would peak at 15,000 rpms and max right around 16,500. Those are $20,000 bomb motors machined beyond what I could ever comprehend. [/QUOTE]
