The Quick Turn Throttle System for Yamaha consists of the ultra-smooth G2 tube with Delrin inserts fitted with a throttle cam (or “pulley”) over 15-20% larger than stock (depending on model). This translates into about 10 degrees less “twist” necessary to reach wide open. To put this into perspective, a 3% change is quite noticeable, so a 15-20% increase will make a significant difference! Also included is a modified Domino throttle housing that provides essential inner clearance for the oversized quick turn tube.
Increasing the size of the throttle cam can affect your riding in several ways. First, your bike’s power characteristics will seem far more responsive – as you turn the throttle, your bike will rev faster than before. Secondly, less overall rotation is required to reach full throttle. This is a huge benefit to riders with limited wrist mobility. In addition, less rotation allows you to more easily maintain a proper riding position with less elbow drop as you crank the throttle.
Keep in mind, this Quick Turn Throttle System has a throttle tube with the unique G2 interlock. This means you can choose from several G2 cam sizes (sold separately) if you decide a change is needed for mud, technical terrain, etc.
Reduced ratio = quicker throttle response for Yamaha bikes. For competition use only.
