How often should fork seals be replaced?

When they start weeping, rather than on a schedule. Riding in dust and sand shortens seal life considerably, and a fork seal saver or regular cleaning of the stanchions extends it.

Can I upgrade the suspension on my Sur-Ron?

Within limits. Springs and oil weight are straightforward and worthwhile, particularly if you are heavier or lighter than average. Full cartridge or shock replacements exist for the popular models. Check fitment against your exact machine.

Why does my bike feel harsh over small bumps?

Usually sag set for the wrong rider weight, or compression damping wound in too far. Both are free to adjust. If it persists after setup, tired fork oil is the next thing to look at.

Sur-Ron forks, shocks & suspension

Suspension is the most under-maintained system on these bikes and the one that most changes how a machine rides. Weeping fork seals become leaking fork seals, and leaking oil onto a front brake is the point at which this stops being cosmetic.

What to know about Sur-Ron forks

Weeping seals do not fix themselves. A film of oil on the stanchion is the early warning. Left alone it becomes a leak, the fork loses damping, and oil ends up on the front disc. Seals are cheap; a crash is not.
Check stanchions before buying seals. Pitting or scoring on the sliding surface destroys new seals almost immediately. Sight down the stanchion in good light before you order anything.
Set sag before you touch anything else. Most riders are running suspension set for someone else's weight. Setting sag correctly is free and changes the bike more than most parts you could buy.
Suspension is where the model money went. Travel varies enormously across the range — 7.9 in on a Light Bee X against 11.4 in on a Storm Bee. If you are being beaten up on rough ground, that is often a model issue rather than a setup one.
