"Cubic inch capacity is replaceable with nothing but more cubic inch capacity"

This is an old saying, but it's message is still relevant! Especially the torque optimized 660 engines profits a lot from this modification.
The power and the torque will rise over the hole range - more power in all situations.You do not have to change any more parts that the piston, cylinder and the gaskets.

· OEM cylinder in exchange

· more power over the hole range

· due to the high class new Low-Friction coating the new cylinder is even more reliable than the stock one

· nobody can see this plus of power on your bike (Police...)

· no more noise on the bike

· perfect in combination with our racing cam and the cylinder head modification.

Our cylinder is a comprehensive remanufacturing to new condition(with bigger bore). The new low-friction plating is a extremly high grade plating that works perfectly with all kind of piston rings. The new honing is necessary concerning the correct running clearance and the surface roughness adequately to the piston rings.
