I just searched online that how to convert Torque into BHP and BHP into torque
Here is a link to this usefull info: Puma Race Engines Technical Guide - Power and Torque - how they are related and how to calculate them
And using above info i also calculated BHP of Yamaha bikes. Only torque info was given there.
Yamaha Royale : 11.16 BHP , Tourque 9.02 N.m. @ 6500Rpm
Yamaha Junoon & Yama 4 : 10.39 BHP , Tourque 8.4 N.m. @ 6500Rpm
DYL Dhoom : 5.14 BHP , Tourque 5.4 N.m. @ 5000Rpm
DYL Motorcycles - Welcome
Honda didnot provide any power info of their bikes on their site, so cant compare them sadly!
