RFX Pro Throttle Tube (Black) Yamaha YZ80/85 83-14  

RFX Pro Throttle Tube (Black) Yamaha YZ80/85 83-14

Product Description

RFX Pro Series Throttle Tubes are machined from billet aluminium and feature a sealed bearing and Teflon sleeve to provide an effortless throttle action. RFX Pro Series Tubes resist damage in a crash unlike standard plastic tubes. For these reasons they are used by many of the top race teams and riders in the U.K Championships such as STR KTM.

  • Replacement throttle tubes for all popular off road bikes.
  • Uses the same cam profile as the OEM part for proper throttle control.
  • Hard anodised billet aluminium construction.
  • Sealed ball bearing and Teflon sleeve virtually eliminate friction.
  • Laser etched with RFX logo.
  • Knurled grip mounted area.
  • Reduced chance of damage if you crash.

Roller Bearing

For an effortless throttle action


CNC Machined Construction

For the ultimate crash resistance

Fitting Instructions

  • Slide the rubber boot down and disassemble the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
  • Carefully remove grip from the old throttle tube if required.
  • Inspect the cables and housing for excess damage or wear, clean and lube them or replace if required.
  • Clean the handlebar and inspect for damage where the old throttle tube has been spinning on the bar if a ridge is present replace the handlebars.
  • Slide the new throttle tube on the handlebar and lube using a penetrating lubricant preferably Maxima MPPL (do not use grease as this attracts dirt and makes the throttle stick after a short period of time).
  • Re-assemble the throttle cables and housing again using some penetrating lubricant.
  • Tighten the throttle housing in the correct position on the handlebars.
  • Adjust the cable to the required (free play amount) of your liking.
  • Rotate the handlebars to their maximum position to check proper operation of the throttle and correct cable routing, some re-adjustment of the cable may be required.
  • Slide the rubber boot back over the housing.
  • Cover the hole in the end of the grip with some electrical tape (To stop glue entering the throttle barrel) and apply a small amount of RFX grip glue to the outer 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 onto the tube.
  • Twist the grip to the correct position and leave to dry.
  • Apply RFX safety grip wire if needed.
  • After the glue has dried again check proper operation of the throttle.
