Just wondering what's red line on the ttr engine am bored and wondering and thanks Brian for quick delivery and surprised me how big the crank bearings are and big end bearing no wonder engine is on hefty side XD

When your filling start dropping out you have hit the red line
8500 rpm I beleive
I agree with Hanzo, but he omitted the word "safe".
The information I have gleaned concerning TTRs indicates that "the safe rpm is 8,500 rpm".
Standard set up is power 28 bhp at 8,500 rpm and torque is 2.8 kg at 7,000 rpm.
Obviously higher rpm are available but at your discretion.
On standard gearing with 14 tooth gearbox and 52 tooth rear, 8,500 rpm equates to 78 mph - plenty fast enough for me at any rate.
