For owners of the bikes nobody catalogs
Search every catalog.
Score every fit.
CrankJay is a self-serve parts finder for classic and hard-to-source motorcycles. Tell us the make, model, year, the part or OEM number, plus a budget and where it ships — we scan permitted public listings, affiliate catalogs, and specialist supplier feeds in parallel, then return candidate matches with a confidence score on every row.
Why this exists
Hours of hand-searching, condensed into one query.
Owners of vintage machines spend evenings cross-referencing fiche PDFs, scanning marque forums, and DM-ing specialist shops to find one part. CrankJay automates that traversal and tells you, on the same row, how confident it is about fitment.
Without CrankJay
- Forty tabs open across hemispheres.
- Forum threads from 2011 with no part-numbers.
- Sellers that won’t confirm fitment, only quote.
- Total: a weekend lost, no purchase made.
With CrankJay
- One structured query: bike, part, budget, ship-to.
- Candidate matches scored on confidence, not just price.
- Seller, asking price, estimated shipping, source — on one row.
- Unverified listings labelled, never promoted.
How it works
One query. Three motions. Candidate matches, ranked.
The same shape every time: state what you need, where, and how much. The system does the cross-referencing so you don’t have to.
What it covers
Twelve marques at launch, broader only as demand proves it.
We seed the index around marques with deep enthusiast queries and documented long-tail SEO demand. Each marque gets dedicated long-tail pages for specific part/model combos, so a search for “CB550 K0 front mudguard 1974” lands on a focused, refreshable page.
- Honda CB / SL / CL (1968–1985)
- Triumph Bonneville / Tiger (1963–1988)
- BSA A10 / A65 / Bantam
- Norton Commando / Atlas
- Kawasaki Z1 / KZ (1973–1985)
- Suzuki GS / GSX (1976–1986)
- Yamaha XS / SR / RD (1970–1984)
- BMW /5 /6 /7 (1969–1985)
- Ducati bevel / Pantah (1972–1986)
- Royal Enfield Bullet
- Ural & Dneper sidecar
- Vintage Moto Guzzi V-twin
What CrankJay is — and is not
Trust comes from what a tool refuses to do.
No stock, no shipping
CrankJay indexes other people’s listings. The seller ships; we never hold inventory.
No guaranteed fit
Every fitment score is an estimate, with confidence tiers and unverified listings clearly labelled.
No spam, ever
One weekly digest on request, performance-only. No promo blasts, no listicles “you might like.”
Spending tied to conversion
Ad budget stays small until affiliate click-through demonstrably pays for itself. The reverse of the usual model.
Affiliate disclosures appear on every listing we surface, alongside the seller, source, and the fitment score. Unverified listings never appear above verified ones.
Pricing
Free to search. Paid when the report earns its keep.
A free tier covers everyday queries; the subscription tunes the score for the bikes you actually own; the restoration report is for projects that justify a long-form, sourced deep dive.
