Pro Series Throttle Sleeve
The RFX Pro Series throttle tubes are machined from billet aluminum and feature a sealed bearing and a Teflon sleeve for smooth throttle operation. The RFX Pro Series tubes are resistant to damage in case of a crash, unlike standard plastic tubes. For these reasons, they are used by many racing teams and top riders in British championships, like STR KTM.
- Replacement throttle tubes for all known off-road motorcycles.
- Uses the same cam profile as the original part for good throttle control.
- Hard anodised billet aluminum construction.
- The sealed ball bearing and Teflon sleeve virtually eliminate any friction.
- Laser-etched RFX logo.
- Textured grip mounting area.
- Reduced risk of damage in case of an accident.

Installation Instructions
- Slide the rubber sleeve down and dismantle the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
- Gently remove the grip from the old throttle tube if necessary.
- Check that the cables and housing are not too damaged or worn, clean and lubricate them or replace if necessary.
- Clean the handlebars and check for damage where the old throttle tube has rotated on the bars; if there is a burr, replace the handlebars.
- Slide the new throttle tube onto the handlebars and lubricate it with a penetrating lubricant, preferably Maxima MPPL (do not use grease as it attracts dirt and causes the throttle to stick after a short time).
- Reassemble the throttle cables and housing using a penetrating lubricant.
- Secure the throttle housing in the correct position on the handlebars.
- Adjust the cable play to your liking.
- Turn the handlebars to their maximum position to check the correct operation of the throttle and cable routing, some cable re-adjustment may be necessary.
- Slide the rubber sleeve over the housing.
- Cover the end of the grip hole with insulating tape (to prevent glue from entering the throttle barrel) and apply a small amount of special grip glue RFX to the outer end of the throttle tube, on the outer diameter.
- Apply a small amount of special grip glue RFX to the inside of the new grip and slide it onto the tube.
- Rotate the grip to the correct position and let it dry.
- Apply brake wire for grips RFX if necessary.
- After the glue has dried, check again that the throttle is working correctly.
