Crash Protection
Frame sliders, engine case covers, axle and tank sliders — the parts you buy hoping never to use. Most track organizations require case covers before they'll let you grid up.
The decision
Case covers first — a holed engine case ends the day and oils the racing line. Sliders second. GB Racing and R&G covers carry race-organization approvals; Woodcraft, T-Rex, and Shogun cover the budget end. A full-bike package runs $250–500 — cheaper than any single OEM fairing.
The brand ladder
