Basic Suspension Set-up
Basic motorcycle suspension set-up is essential to your safety and overall riding experience. Here are a few key points from within the complex motorcycle suspension.
The first is maintenance. Greasing of the suspension pivot points is critical. Having free movement in a suspension is the first part of the complete set-up.
|Normal Conditions||Muddy Conditions|
|Steering Head||35 Hours||25 Hours|
|Suspension Pivot||35 Hours||25 Hours|
The fork oil viscosity is critical to the damping curve of your suspension. When oil viscosity breaks down it creates more wear on the internal suspension components. The two together change your suspension over time, which is why routine maintenance is critical. The following are the recommended schedules:
|Forks||20 Hours||40 Hours|
|Shock||20 Hours||40 Hours|
We have found significant gains when running high performance fluids. Proper fluids will save you from expensive repairs in the future.
This is critical to the safety and performance or your new suspension. If the forks are not centered they will bind. This will change performance and create premature wear.
Measurement A: Place bike on a stand, wheels free of any contact. Measure from the left inside the bolt to a point on the rear axle. Mark this point so you can return to it for all measurements.
Measurement B: Place bike on the ground, with rider in full gear on the bike in normal riding position, feet barely touching the ground. Measure the same two points.
The following measurements (for both A and B) are good starting points, however they are only recommendations. Whenever possible you should have an experienced technician set up your bike for you.
|50cc - 65cc||85cc - 100cc||125cc - 450cc|
|Race Sag||70-75 mm||95-105 mm||102-108 mm|
|Static Sag||25-35 mm||25-35 mm||30-40 mm|
