Product Usage Instructions:

Ace Wheel Spoke Torque:

1. Perform a break-in run after initial use to check spoke
   torque.

2. For break-in:

   • Run at low speed, check spoke torque every 15 minutes for 3
     times.

   • Gradually increase speed and impact of jumps and landings.

3. Check spoke torque before riding; adjust if necessary.

4. Ensure even tension throughout the spokes.

Ace Wheel Maintenance:

1. Remove wheel runout if it increases for better
   performance.

2. Clean tire mounting surface after riding on muddy or sandy
   terrains.

3. Regularly check and replace bearing if rotation fails.

4. Replace worn-out collar axle for optimal performance.

5. Regularly check and tighten mounting bolts for sprocket and
   brake disc.

6. Use OEM products for sprocket and brake disc mounting
   bolts.

7. Avoid prolonged exposure to UV rays to prevent color
   fading.

Frequently Asked Questions (FAQ):

Q: Can I use the Ace Wheel for regular street riding?

A: No, the product is intended for racing use only in closed
areas.

Q: How often should I check the spoke torque?

A: Perform a break-in run after initial use and check spoke
torque before each ride. Adjust as needed.

Q: What should I do if the wheel runout becomes larger?

A: Remove the wheel runout to improve vibration and handling.
Refer to the OEM service manual for criteria values.

Q: How can I prevent color fading of the product?

A: Avoid leaving the product outdoors for extended periods,
especially in direct sunlight with UV exposure.

Instruction & Maintenance Manual
Ace Wheel Overview

1. This product is intended for racing use only and for use in closed areas.
2. Failure to understand the product may result in fatal accidents. 3) Installation and maintenance should be performed by a professional mechanic who understands
   the characteristics of off-road bikes.
   Ace Wheel Spoke Torque
3. Since the spoke torque of a new wheel varies greatly after it is first used, be sure to perform a “break-in run”. Note:

a) For break-in, run at a low speed and check the spoke torque every 15 minutes. Perform this step 3 times.
b) Gradually increase the speed and impact of jumps and landings. c) Careful “break-in run” will ensure that the wheels retain their performance for a long time. d) The set spoke torque: FR= Minimum 4.0 Nm and RR= Minimum 4.0 Nm. 5) Wheel offset is as follows:
i) KTM: Front=25mm & Rear= 53mm ii) YAMAHA: Front=27.3mm & Rear= 48.6mm iii) 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).
6) Check the rim for cracks and spoke torque before riding. 7) In case the spoke torque is higher than the set torque, loosen the nipple and adjust the torque
in the tightening direction. 8) Eliminate uneven tension throughout the spokes.
Ace Wheel Maintenance
9) 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.
10) 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.
11) Check the dust seal regularly. In case there is dirt inside the collar axle, the dust seal may be worn out.
12) Check the bearing rotation regularly and replace the bearing in case it has rotation failure. 13) 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. 14) 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. 15) 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.
