Front Fork Leaking Oil — $80–$250

Oil seeping from the front fork seals is very common on Singapore bikes due to heat cycling and road grime. Leaking forks contaminate the front brake disc — a safety hazard.

Fix: Fork seal replacement: $80–$200 at most SG workshops. Do not delay.

Harsh / Stiff Ride on Singapore Roads — $40–$120

Singapore's speed bumps and uneven roads expose poor suspension setup. Most bikes come factory-set for heavier Western riders — need adjustment for lighter SG riders.

Fix: Set sag (static + rider sag). Most bikes have preload adjustment on the rear shock — reduce preload for softer feel. Front forks: oil change + viscosity adjustment.

Bottoming Out on Speed Bumps — $100–$400

If the bike bottoms out on every speed bump, the shock absorbers are worn or the spring preload is too soft for your weight.

Fix: Increase rear shock preload. If bottoming persists, the shock is worn and needs replacement or a service (rebuilding with fresh oil).

Bike Wobbles at Speed — $60–$200

A wobble or weave at highway speeds (above 80 km/h on PIE/CTE) indicates tyre imbalance, worn steering head bearings, or incorrect suspension setup.

Fix: Check tyre balance and pressure first. If tyres are fine, check steering head bearings for play. A worn bearing causes speed wobbles. Workshop inspection required.
