Is there anyway to lower the rpm on my xA 4K at 80 is scary.

I know I could let off the gas and change the transmission but is their anything else??

 

change your gear ratio, other then that i just go use too it engine handles just fine at that spd

 

Larger diameter tires will change the RPM, but it affects the accuracy of the speedo, puts more wear and tear on the motor and drivetrain and also wheel/tire clearance could be affected.

 

only if improperly sized. the correct offset and tire wheel combo will not affect the speedo that much.

 

^^^I understand that, but if someone were to drastically change the tire diameter to lower the RPM at 80, it would affect the speeo more. If you go with a HUGE tire, it will lower the RPM....but there are negative affects.
