Using a large/performance throttle body is like upgrading the carburetor for a EFi Fuel injection motorcycle. If you have a big bore kit or cylinder head/big valve upgrade to your motor, the SWR Sunworld Racing throttle body will help to further improve your engine air intake affordably. Throttle body made in a few different sizes - 32/34/36mm to suit your motor.
For CBR150/CB150R models, you will need to reuse and port the stock intake manifold together with this racing throttle body.
