Product Usage Instructions

Ace Wheel Spoke Torque
Before using the wheel, ensure the spoke torque is set to the minimum required values. Perform a break-in run by running at low speed and checking spoke torque every 15 minutes for three cycles. Gradually increase speed and impact of jumps and landings for optimal performance.

Wheel Inspection and Maintenance
Regularly check the rim for cracks and spoke torque before riding. If the spoke torque is higher than the set value, adjust as needed. Ensure even tension across all spokes.

Ace Wheel Maintenance
Regular maintenance is essential for optimal performance. Remove wheel runout if it becomes excessive to improve handling. Clean the tire mounting surface after riding on muddy or sandy terrains to maintain spoke torque stability.
Check the dust seal, bearing rotation, and collar axle regularly for wear and replace if necessary. Use OEM mounting bolts for sprockets and brake discs and tighten them regularly.

FAQ

1. Can I use the Ace Wheel for casual riding?
   No, the product is intended for racing in closed areas only.

2. How often should I check the spoke torque?
   Check the spoke torque every 15 minutes during a break-in run and regularly thereafter before riding.

3. What should I do if the spoke torque is higher than the set value?
   If the spoke torque exceeds the set value, loosen the nipple and adjust in the tightening direction.

4. How should I clean the tire mounting surface?
   After riding on muddy or sandy surfaces, clean the tire mounting surface to prevent instability of spoke torque.

5. When should I replace the collar axle?
   The collar axle is a consumable part and should be replaced when it shows signs of wear.

Instruction & Maintenance Manual

Ace Wheel Spoke Torque

• 4. Since the spoke torque of a new wheel varies greatly after it is first used, be sure to perform a “break-in run”.

Note

• For break-in, run at a low speed and check the spoke torque every 15 minutes. Perform this step 3 times.
• Gradually increase the speed and impact of jumps and landings.
• Careful “break-in run” will ensure that the wheels retain their performance for a long time.
• The set spoke torque: FR= Minimum 4.0 Nm and RR= Minimum 4.0 Nm.

Wheel offset is as follows:

1. KTM: Front=25mm & Rear= 53mm
2. YAMAHA: Front=27.3mm & Rear= 48.6mm
3. HONDA: Front=27.8mm & Rear= 49.3mm

***** Note: Measuring distance of wheel offset to be:
Front= (Between mounting surface of brake disc and edge of rim)
Rear= (Between mounting surface of sprocket and edge of rim).

1. Check the rim for cracks and spoke torque before riding.
2. In case the spoke torque is higher than the set torque, loosen the nipple and adjust the torque in the tightening direction.
3. Eliminate uneven tension throughout the spokes

Ace Wheel Maintenance

1. Remove the wheel runout in case it becomes larger, which can improve vibration and poor handling problem.
   Note : Regarding the criteria value of radial / lateral runout, refer to the OEM service manual.

2. When riding on muddy or sandy surfaces, mud and sand can get into the tire mounting face (under the rim strip). This can cause instability of spoke torque so clean the tire mounting surface after each ride.

3. Check the dust seal regularly. In case there is dirt inside the collar axle, the dust seal may be worn out.

4. Check the bearing rotation regularly and replace the bearing in case it has rotation failure.

5. The contact point between the lip of the dust seal and the collar axle is subject to wear. Note that the collar axle is a consumable part and should be replaced when it’s worn out.

6. The mounting bolts for the sprocket and brake disc should be OEM product. They should be checked and tightened regularly.
   Note : As for the sprocket, OEM or OEM-type product should be used.

7. Due to the characteristics of the product, the color of this product may fade significantly under the influence of ultraviolet rays and other factors especially where it’s left outdoors for long periods of time.
