One inbox, read by the people who research the specs. Plain email, no ticket numbers. Corrections and bike requests get read first.
Frequently asked
What is TOSPEC?
A per-bike maintenance-specs reference for sport motorcycles: oil, filters, pads, chain, plugs and fluids, with every fact sourced, dated, and shown next to the manual or catalogue it came from. Plus Check my bike — a tool that reads any oil against your bike's spec and shows the pads, fluids and chain that fit it.
Is it free?
Yes. No paywall, no account, no sign-up. Nothing to log into, because there is nothing we ask you to log into.
How do the buy links work?
Buy links go to retailer search results. Some are affiliate links: if you buy after clicking one, the retailer may pay TOSPEC a small commission at no extra cost to you. Commissions never decide which parts, oils, or bikes we cover.
Do you store my data or track me?
No. No analytics, no pixels, no cookies from us, and no accounts. Check my bike runs in your browser; a reminder you create is a calendar file generated on your device and nothing is sent to us.
I found a wrong number. What now?
Tell us — a wrong spec, a dead source link, a fitment gotcha we missed. Name the bike and the fact. Corrections get read first, and if you send one we can verify, we credit you on the page.
