Some links may earn TOSPEC a commission at no cost to you. Prices shown are typical street prices for consumables (oil, pads, chains, filters, fluids) — always verify fitment and price at the retailer.
Oil capacities are the manufacturer's with-filter-change figure, not the dry-rebuild total that circulates online. Always verify against your own owner's manual before you turn a wrench — this is educational reference, not a repair procedure.
