This RPM can be install on any bike which don't have RPM its electronic, years back i used it on CD-70 but now i modded and used it on this bike. i don't remember the exact price 400 500 ka mil jye ga.
Ummmm the science behind this RPM is this that the wires go to head lamp i don't exactly know because i paid to install this. in a few days maybe i'll open the lamp than surely i will capture a pic for you.
