Throttle Kit Installation Instructions
Throttle Bearing Kit Installation
Before you begin
Your throttle tube must have a solid closed end with a center hole at least 6 mm in diameter.
This hole is required for proper fit and retention of the assembly.
Installation Steps
-
Prepare the grip
With the grip installed on the throttle tube, cut a clean 5 mm hole through the end of the grip to match the hole in the throttle tube.
2. Load the assembly into the installation tool
Place the complete throttle kit into the installation tool provided.
3. Separate the bolt and bar end
Use a 6 mm Allen key on the side of the tool and a 4 mm Allen key on the bar end to loosen the assembly and remove the bolt.
Keep the tool facing upward so the internal components remain inside the tool.
4. Insert the bar end and bolt
From the outside of the throttle tube, place the bolt and bar end through the grip and into the throttle tube.
5. Thread the internal assembly
Insert the installation tool (holding the internal components) into the inside of the throttle tube and thread it onto the bolt.
Tighten until snug and secure.
6. Remove and keep the tool
Pull the installation tool out and store it safely.
You will need it again when changing grips or throttle tubes.
7. Install the handlebar bushing
Insert the plastic bushing into the handlebar, it should be slightly snug, use o-rings if required:
13.9 mm to 14.5 mm inner diameter: no o-rings required
14.5 mm to 14.9 mm: install the O-rings in the groove
Tighten the bushing with a 4mm allen key until its slightly snug, do not overtighten.
8. Lubricate the bushing contact points
Before installing the throttle, apply a small amount of grease to the inside of the bushing as well as the outside lip of the bushing for the smoothest operation.
9. Install the throttle assembly
Slide the complete throttle assembly onto the handlebar, ensuring it fully seats into the insert.
