The KTM RC 390 is a popular sportbike known for its agility and performance. However, some riders may find the stock seat height to be too tall. If you’re one of those riders, lowering your RC 390 can improve comfort and confidence, especially if you’re shorter. This comprehensive guide will walk you through the step-by-step process of lowering your RC 390 safely and effectively.
Materials and Tools
Before you start, gather the necessary materials and tools:
- Socket wrench set
- Allen key set
- Torx wrench set
- Rear shock spanner wrench
- Measuring tape or ruler
- Patience and attention to detail
Safety Precautions
- Park the motorcycle on a level surface and secure it with a center stand or paddock stands.
- Disconnect the battery to prevent any electrical shorts.
- Wear appropriate safety gear, including gloves and safety glasses.
Step 1: Measure the Stock Ride Height
Measure the distance from the ground to the top of the rear seat. This will give you a baseline for comparison later.
Step 2: Remove the Rear Shock
Use the socket wrench to remove the bolts holding the rear shock in place. Carefully slide the shock out of the motorcycle.
Step 3: Adjust the Rear Shock Preload
Locate the preload adjuster ring on the rear shock. Turn the ring counterclockwise to reduce preload, which will lower the rear of the motorcycle. Measure the distance from the ground to the top of the rear seat again to ensure you have achieved the desired lowering.
Step 4: Reinstall the Rear Shock
Slide the rear shock back into place and tighten the bolts securely.
Step 5: Adjust the Front Forks
Loosen the pinch bolts on the front forks using the Allen key. Slide the forks down slightly to lower the front end of the motorcycle. Tighten the pinch bolts again.
Step 6: Adjust the Side Stand
The lowered ride height may affect the length of the side stand. Use the Allen key to adjust the side stand to the correct length to ensure the motorcycle stands upright.
Step 7: Reconnect the Battery
Reconnect the battery and check all connections to ensure they are secure.
