This engine has nothing to do with the old XL XLR

It is an evolution of the CG125. Honda reduced the weight of the piston by reducing its height and reducing the diameter of shaft 15 to 13mm

Of shots, none of the old kits can be mounted even as the hole in the crankcase can not spend a bigger shirt

We get very good results by increasing the duration of valve opening and increasing the compression

Parts supplied: - Camshaft ground in France according to our exclusive profile
- Your cylinder on which we have reduced the height
- Cylinder head gaskets, header and exhaust
- Manual winding

PROCEDURE: You must dismount and send us your cylinder and the cam shaft so that they are altered. Within 8 days we will retu you with the necessary parts to reassemble

Please note that the changes of the technical characteristics of a vehicle results in a lack of conformity which may prohibit its use on public roads
