Honda’s groundbreaking CB750 Four not only demonstrated Japan’s ability to produce sophisticated large-displacement motorcycles but also sparked a thriving aftermarket industry for performance and custom parts. In the 1970s, numerous CB750s were transformed into choppers and café racers.
One exceptional custom creation was “Sentoh,” crafted by AFT Customs for the 2011 World Championships of Custom Bike Building in Sturgis, South Dakota. The motorcycle, titled as a 1975 model, underwent extensive modifications, with a reworked perimeter-style frame featuring a suspended fuel tank and a rear seat cowl serving as the oil tank. The engine was upgraded with an 836cc kit and a single Mikuni carburetor attached to a custom four-tract intake manifold. Sidewinder-style head pipes wind through the frame alongside the cylinders and lead to Leo Vince exhaust canisters.
The bike’s suspension was updated with Yamaha YZF-R1 inverted forks at the front and Race Tech shocks at the rear, working through a braced swingarm. Modern Beringer brakes, including a six-piston caliper at the front, ensure reliable and safe stops for Sentoh.
