Rare bird: The Crampton P3 Classic Cafe.


Little is know about Ian Crampton's Limited batch of Cafe Racers based on the Triumph Speed Triple, but here's what the lads at Triumphrat forum could piece together:
"Crampton P3 "Classic" Prototype

A working prototype for an exclusive, limited edition, hand-built motorcycle
made in England using British parts wherever possible,
combining traditional appearance and craftsmanship with modern performance levels.

Provisional specification as follows:

Engine: 3 cylinder 955cc 12 valve DOHC with electronic fuel injection, supplied by Triumph Motorcycles. Tuning to customer specification.

Chassis: Sifbronze welded Reynolds 531 tubular steel spaceframe, powder coated (prototype is painted) with engine as fully stressed member.

Front suspension: Sifbronze welded Reynolds 531 tubular steel girder fork, nickel plated (prototype is painted), with rising-rate linkage to double-adjustable gas-filled spring/damper unit with remote reservoir, supplied by Ohlins.

Rear suspension: Sifbronze welded Reynolds 531 tubular steel double-sided swinging-arm, nickel plated (prototype is painted), with rising-rate linkages to twin double-adjustable gas-filled spring/damper units with piggy-back reservoirs and hydraulic preload adjustment, supplied by Ohlins.

Colours: To customer specification.

Front brakes: Twin 320mm floating discs with six piston calipers, supplied by PFM.

Rear brake: Single 260mm fixed disc with four-piston caliper.

Front tyre: 120/70-R17, supplied by Avon Tyres (or to customer specification).

Rear tyre: 180/55-R17, supplied by Avon Tyres (or to customer specification).

Rake/trail: nominally 24o/85mm

Seat height: 720mm

Weight: 172kg

This is a fully working prototype, not a design concept. After testing and development, a batch of twenty replicas will be made for sale, price £15,000 + vat.

For further details contact Crampton ltd at Melisande House, 75, Spring Hill, Arley, Coventry CV7 8FE or "

Other notations were that the actual fuel tank is under the seat; the tank-looking is a cover for the engine's air box. Sadly there is no Website for the Crampton and it has seemed to be lost and no word has been mentioned of it since 2004...

I met Ian Cramp, designer and manufacturer of the hand built Crampton Cafe Racer at the NMM near Birmingahm in July 2005 and later went back to his place where he showed me his workshop. He was at that stage still taking orders for the Crampton as well as doing custom race engineering work for both period and modern racers. Interesting guy, a former journalist for Fast Bikes magazine, where the story of the design of the prototype Crampton was serialised. We have one thing in common - we both race vintage Velocettes.
