RFX Kawasaki/Suzuki/Yamaha 4T Throttle Tube

Sport Series Throttle Tubes

RFX Sport Series throttle tubes are an exact replacement part at a fraction of the cost of genuine parts. They have been manufactured with a Teflon-coated nylon fabric to ensure a smooth feel and fit.

• Replacement throttle tubes for all popular off-road motorcycles.
• Uses the same cam profile as the OEM part for proper throttle control.
• Teflon-coated nylon fabric provides smooth action.
• Does not damage handlebars like aluminum tubes.
• Open-end design for use with aluminum handguards if required.

Fitting Instructions

• Slide rubber boot down and unbolt the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
• If required, carefully remove the grip from the old throttle tube.
• Inspect cables and housing for damage or excessive wear, clean and lubricate or replace if necessary.
• Clean the handlebar and check for any damage where the old throttle tube has been spinning on the bar, if there are any raised burrs, replace the handlebar.
• Slide the new throttle tube onto the handlebar and lubricate using a penetrating lubricant, preferably Maxima MPPL (do not use grease, as this attracts dirt and causes the throttle to stick after a short period of time).
• Reassemble the throttle cables and housing using some penetrating lubricant.
• Tighten the throttle housing into the correct position on the handlebar.
• Adjust the cable to your preferred length.
• Turn the handlebar to its full lock position to check for correct throttle operation and correct cable routing; the cable may need to be re-adjusted.
• Slide the rubber boot back over the housing.
• Cover the hole in the end of the grip with electrical tape (to prevent glue from getting into the throttle tube) and apply a small amount of RFX grip glue to the outside end of the throttle tube on the outside diameter.
• Apply a small amount of RFX grip glue to the inside of the new grip and slide it onto the tube.
• Rotate the grip into the correct position and allow to dry.
• Apply RFX lock wire if required.
• After the glue has dried, re-check for correct throttle operation.
