Check my bike
One bike, six jobs, one verdict language. Every tab checks the real products against your bike's own spec — oils against the manual's chart, pad compounds against your calipers, fluids against the reservoir cap, coolant against the track rulebook, chains against the factory pitch, tires against the factory sizes — and sorts them Safe, Conditional or No, with the reason in the manufacturer's own words. Every fact sourced and dated.
Pick a bike above, then a job tab — oil verdicts, pad shapes, fluids and chain data all render here. With JavaScript off, the flagship summary below still shows what each bike's manual asks for.
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.
What the tiers mean
On viscosity and heat
A heavier grade that's still inside your manufacturer's own temperature chart is a legitimate choice for sustained heat or hard track use — not a hack, and not an upgrade. Outside that chart, nobody with an engineering stake in your engine backs it. The oil check only clears grades your manual's chart already allows.
What five flagships ask for
| Bike | Viscosity | JASO / API |
|---|---|---|
| Yamaha YZF-R1 | 10W-40 | MA · API SG |
| BMW S1000RR | 5W-40 | MA2 · API SJ |
| Kawasaki Ninja ZX-10R | 10W-40 | MA · API SG |
| Suzuki GSX-R1000 | 10W-40 | MA · API SJ |
| Honda CBR1000RR | 10W-30 | MA · API SG |
Every oil verdict is checked against the JALOS JASO T903 registered-oil list — the registry that says whether an oil's JASO claim is filed, not just printed on the bottle.
