Reducing Friction in Engines
Increase the strength, durability and life of your motorcycle engine.
This picture shows most of the moving parts in a typical Inline-4 motorcycle.
One of the optimum performance modifications we do is a surface treatment of each individual component. Not only does it dramatically reduce friction, but it also increases reliability. M-Tech uses a specialized metal finishing process that removes imperfections, therefore increasing parts life and engine & transmission performance.
Shifting is dramatically improved.
Any 2-stroke or 4-stroke engine will benefit – Single, V-Twin or 4-Cylinder. Contact us for an estimate.
