Warning!

Neither www.rc51.org or it's members make claims to the validity of this modification nor does anyone involved with this website take any responsibility in the event of damage to your motorcycle as a result of this modification.

If you make this mod you do so at your own risk.

Having said that, the soft-limiter was not placed on the motor of the US Spec RC51's for any reason that
you might associate with preventing harm to the motor. The real reason is known by a few, but I
cannot divulge the info without breaching the trust of those contacts I have in the industry so don't ask
