Diamond Plateau Honing Services: Perform at Your Bike’s Best

OEM to overbore, U.S. Chrome’s custom 2 Stage-Diamond Plateau Honing process makes the straightest, roundest cylinder bores with a diamond-hard surface for the best oil retention and lubricity possible. Almost every cylinder we work with can be restored to Standard Factory OEM bore size. In nearly every case your cylinder can also be overbored and re-plated to accept a larger piston size for increased displacement and more horsepower. In either case, our motorcycle cylinder boring specialists start by increasing the diameter of your cylinder to make sure the bore is free of taper or out-of-round condition prior to plating. The end result is the hardest, toughest, roundest, and straightest bores in the powersport industry, period. Our highly qualified technicians can match any clearances and specifications you need to get the maximum horsepower from your bike. It doesn’t matter what you ride or where, from Harley to Ducati, we want to put you back where you belong – pushing your bike to the limit!

Our in-house porting expert, Ryan Callies, has almost two decades of experience porting and modifying motorcycle cylinders and heads, and he is happy to share that experience with you in a professional, friendly manner. Cylinders can be race-ported or trail-ported for only $125 per bore! Contact Ryan at 1-866-922-5066 ext. 109 for any technical questions about cylinder porting ideas.
