Even though Suzuki's GSX-R600 sport bike is better suited for smaller riders -- fitting nearly anyone under 6 feet tall -- some people may need to lower the motorcycle to allow them to sit on the machine comfortably. While a slight decrease in the motorcycle's height can be found by adjusting the rear shock absorber's spring preload, doing so will adversely affect the GSX-R's maneuverability and its ability to handle harsh road conditions. Alternatively, lowering the front fork and installing an extended linkage, which connects the shock absorber to the swingarm, will accomplish the task without drastic handling changes.

Lift the motorcycle's rear wheel off of the ground, using a swingarm stand.
Slide a hydraulic jack beneath the motorcycle and centre it below the rear shock absorber. Raise the jack to lift the shock absorber slightly, relieving the pressure on the shock absorber and its link.
Unscrew the nut from the shock absorber side of the links, using a 14mm socket. Pull the bolt out from the link to free the shock absorber. Remove the linkage bolt and nut from the swingarm end of the link, using a 14mm socket. Pull the link away from the motorcycle.
Install the new lowering link onto the rear shock absorber first. Place the link around the shock absorber and slide the stock bolt through the link and shock absorber. Screw the nut onto the link bolt loosely, using a 14mm socket.
Raise the jack as needed to align the swingarm and free end of the lowering link. Slide the link bolt through the link and the swingarm. Screw the nut onto the link bolt and tighten it, using a 14mm socket.
Tighten the shock absorber's link nut completely, using a 14mm socket.
Lower the motorcycle's rear wheel to the ground.
Installing the Lowering Link
Lift the motorcycle's front wheel off of the ground, using a fork clamp stand.
Loosen the upper and lower fork clamps' pinch bolts, using a 6mm Allen wrench.
Grasp the upper fork legs and lift the fork up into the fork clamp. Stop when the upper fork leg extends a half inch above the upper fork clamp.
Tighten the pinch bolts on the upper fork clamps, using a 6mm Allen wrench. Check that both upper fork legs are evenly extended above the fork clamp. Loosen the upper fork clamp pinch bolts, using a 6mm Allen wrench, and adjust the fork height as needed.
Tighten the lower fork clamp's pinch bolts, using a 6mm Allen key. Lower the front wheel to the ground.
Lowering the Front Fork
Tips and warnings
- Lowering the motorcycle will drastically alter its maneuverability and suspension settings. Ride the motorcycle carefully until you are comfortable with its new steering traits.
- Don't raise the front fork more than 1 inch to lower the front end. Excessive changes will negate the motorcycle's stability on the road.
