Our throttle linkage for SF/OBX-pattern throttle bodies replaces the conventional throttle lever with a non-linear progression quadrant, which increases control at small throttle openings. Fits GMR SF/OBX bodies and Jenvey® SF bodies.
Want this, but not quite like this?
A different size, a bore spacing we don’t list, a port shape to
suit your head, a fitting somewhere else — we make these ourselves, so most of it is
a drawing change rather than a new product. Tell us what you need and we’ll price it.

Key features
Smooth as silk: Our throttle quadrant enables direct actuation of the throttle, no stiff or sticky movement when battling with convential linkage types.
Simplicity at it’s best: Only 3 main components make up our linkage, the quadrant, cable mount and cable guide. Conventional linkages have up to 10 different components all needing adjustment.
Controllability: The quadrant is shaped such that partial throttle progression is slower than full throttle progression giving much more control over sensitive torque areas of low throttle opening.
Reliability: Fewer parts matched with fully guided cabling results in a smoother and more durable setup.
Single adjustment: The only adjustment required is to tension the cable using the easy to adjust cable adjuster on the cable guide. No rose joints to wind in and out and no hole positions to change.
Direct fit and replacement: Our Quadrant directly replaces the throttle lever. We can produce it with any throttle cylinder spacing, left or right hand, (facing the velocity stack end).
Lead time: these are made to order.
