Bultaco Montjuich Class 340 TSS Competition Client
May 2026
In the 70’s & 80’s Californian petrol heads invented a new racing class, so the myth suggests, half way between circuit road racing and dragster style Standing Quarter Mile. i.e. the Standing Mile termed the “Montjuich Class”. This required hybrid motorcycles half way between circuit racers and standing quarter types.
Under Jeff Duval’s overseeing stewardship, the scoot was handcrafted from scratch by John Parry of Cobra Frames with, for starters, 7/8th chromoly, 5” stretch, 37 degree rake frame for that Monterey Class allure.
On the mech side of things, a full race 350 SSR motor entirely rebuilt from scratch by two stroke guru Jean-Francois Vicente, with higher tech new or custom machined parts. Emphasis is on optimisation and usability instead of all out incontrollable power!
JETS’ Bultaco 350 SSR currently being restored to its former glory is a good example of that iconic but ephemeral “Montjuich Class”. More similar rebuilds in the pipeline…
Technical Specs
Design & Build:
Concept, Design, Sourcing & Financial Recklessness: Jeff Duval
Build: John Parry(Cobra Frames)
Driveline engineering: Jean-Francois Vicente
Engine
Fully rebuilt 340 TSS competition engine, re-engineered by Bultaco Guru Jean-François Vicente.
Incorporates high-spec modern internals and bespoke machined components throughout.
The brief was simple—at least on paper: “Optimise everything… except common sense.”
Result: strong, precise, and eminently usable power!
Transmission
Period-correct 5-speed gearbox, rebuilt and calibrated in harmony with the engine.
Shift quality: reassuringly mechanical. Tolerance for abuse: allegedly improved.
Truth: best treated with respect… and occasional charm.
Chassis
Handcrafted, one-off frame by John Parry. 7/8” chromoly construction, +5” extended geometry and 37° rake
All of which contributes to that elusive balance between Mediterranean eleganceand Californian mischief.
Suspension & Steering
Front: Ceriani 35mm competition forks (adjustable) by CR Suspension KftRear: Custom units also by CR Suspension Kft (Budapest)
Set-up philosophy: compliant when asked… uncompromising when required.
Wheels & Brakes
Chromed alloy wire wheels: 21” front / 18” rear. Stainless spokes throughout. Full Beringer competition braking system & controls. K-Tech 11.5” floating discs
Stopping power described by some as “reassuring”… by others as “a polite but firm suggestion to reconsider one’s enthusiasm.”
Instrumentation
In a moment of unexpected maturity, the decision was taken to make the machine road legal.
Electronic speedo/tacho (model deliberately understated) Complete bespoke wiring architecture by John Parry in collaboration with Dave Norris of WIRED-IRON.
Bodywork & Seating
Designed and executed in close collaboration between:
- Jeff Duval
- John Parry
- Jean-François Vicente
A study in restraint—if one accepts that restraint can occasionally include a racing stance and a hint of taunt!...
Ergonomics
A competition-derived riding position… subtly civilised for road use.Suitable for: seasoned riders, committed enthusiasts, and… optimists! Less suitable for chiropractors (though business may follow)
Photography
Entrusted to Max Howard a photographer capable of capturing not merely the machine… but the slightly unreasonable ideas that led to its existence.
Finish
Hi-pol metal polishers & finishers of Fareham & Chromers SilvaBronz of Beckworth for those crazy but hugely important final touches!
Bultaco Racing Team Paintwork by Image Custom Design (Camberley) — Tom, Steve & Mandy.
A masterful homage to the late Jeff McCann, whose influence still lingers wherever paint dares to be more than colour.
Execution: precise, confident, and entirely free of nostalgia’s heavier clichés.
