This 4-piston brake caliper from Racing Boy has been fitted to Suzuki Shogun bike which is featured in Malaysian Cub Prix Championship. This fitting means that 4-piston caliper is already enough for racing.
Racing Boy 4-piston Caliper fits very nicely with this Racing Boy 300mm disc plate. As you can see from the picture above, the brake pad of the 4-piston caliper grip the 300mm disc plate and gives a nice brake line feature on the disc plate. Usually, the wrong fitment of the caliper and disc plate will make the disc plate only being gripped on the outer side by the brake pad.
