Why choose HMF?

Founded in 1997 in Cleveland, Ohio, by Hans Luenger, HMF (Hans Motorrad Factory) builds its exhausts in the USA from stainless steel or aluminium, including for ATVs and UTVs. It won its class at the Baja 1000 in 2005 and 2018.

When should you replace this part?

A scored or oval cylinder, or one with damaged plating, loses compression and wears the piston quickly. Measure the bore at every top-end rebuild: beyond the wear limit the cylinder must be replaced or resleeved.
