NSR 250 modofied performance heads

[WarrenW]

You are buying a PAIR of heads for the MC21 or MC28 NSR 250cc two stroke motor.

These heads have been especially machined to reduce the combustion chamber size. Coupled with the right pipes and PGM3 etc, these are capable of boosting the horsepower significantly to achieve above 70 horsepower with ease.

Expertly machined to close tolerances. The bike they were fitted to was transformed by these heads.

A MUST HAVE performance part for your MC21 or MC28 engine !!

You will not find another pair of heads like these around for this price. Be in quick as they will not stay here for long!

Overseas inquiries welcomed. Shipping costs will vary to the destination.

This is the CHEAPEST HORSEPOWER you will ever buy.
