lol, not good, my current 110 kmph RPM can go to 4.5k. Clutch is slipping and bearings/forks must have rattled themselves to bits. Too many launches

Time to upgrade to Exedy Carbon-D Single!

I think you can pay the likes of PAR or PPG to make you a custom gear set.

But yeah, about 15000 ringgit for a set of 4 gears.

Once the clutch is fully coupled, the RPM vs the KM/PH don't matter much, it's down to the gearbox, differential and wheels to determine the RPM. The RPM at a certain speed doesn't determine power or efficiency of the vehicle, or even it's fuel consumption. This is dicated by the final drive ratio.

If you want a lower RPM for the speed you're driving at, just get bigger tyres lol, since the radius is bigger, you get less RPM, but remember to calibrate your speedo.

Time to save up for an OSGiken gearset lol.
