RPM Calucation based on torque and BHP
max troque 7000RPM Max power 9000RPM ft 2016
40% of 7000RPm 28000
Idle RPM
50% of Max Power Torque 9000 = 4500
RPM Range: 2800-45000 (to charge bike battery KTM recommended above 4000RPM)
Max Power at 9000RPM
We don;t need go above 9000 RPM we already got max power.
Max torque at 7000RPM
We don;t need go above 7000 RPM we already got max torque.
Motorcycle Idle RPM
The ideal idle RPM (revolutions per minute) for a motorcycle is typically between 700–1,000 RPM. However, this can vary depending on the make and model of the bike. You can find the recommended idle RPM for your specific motorcycle in the owner’s manual.

foot pound vs NM
One foot-pound (ft/lb) is equal to 1.356 newton-meters (Nm). To convert newton-meters (Nm) to foot-pounds (ft/lbs) all you need to do is divide your figure (Nm) by 1.356

max RPM Issues
Higher Frequncy of volves, Piston repaeats may damage the engine. Timing chain tensioner fails, Cam shaft, crank sahft synchronization failes etc. valves may direct contact with piston due high repeats springs may not fast as. and engine blow. that;s why red celings.
Piston speed
Why redline in the tachometer?
The red line on a tachometer indicates the maximum engine speed at which an internal combustion engine can operate without causing damage.
