Over the last few month's Scotty Finlay (FRP) has been hard at it working on this clutch system to deliver you the very best from your engine.
With the advent of more and more powerful engines coming onto the market. He seen the need to transfer more power from the engine to the wheels more efficiently.
With the Pro-MX clutch system Scott has taken already proven technology from his primary field of expertise. (Minimoto's)
During development of the Pro-MX clutch system he seen the need to break the current mold of 54mm clutch's and developed the 70mm fully adjustable clutch.
By changing the ratio between the engine and the drive wheels. (as shown below)
The engine can deliver more power to the drive wheels. (As shown below)
Providing faster acceleration (As shown below)
We know how much you like to tinker so we gave you more options than you thought possible.
Even with the most highly strung of engines, the infinitely adjustable Pro-MX clutch system will allow you to be able to dial it in to perfection.
The clutch's bite point is set by pre-loading the springs
Spring adjustment tool.
The way the clutch sustains slip is adjusted by using different spring thicknesses.
From left to right 1.6mm Green, 2.0mm Yellow, 2.3mm Blue, 2.5mm Red
Further fine tuning can be made by adding weight to the BZM shoes.
The Pro-MX system
The housing is manufactured from high quality aircraft grade aluminum.
A unique feature we have designed into the back housing is the ability install the systems to both Zen, CY and BZM without any modifications. By way of a reversible locating ring.
The clutch back plate itself. Is manufactured from 7075 T6 heat treated aluminum.
Here are the components that come together to make the clutch assembly.
Clutch fully assembled.
How does this clutch compare to the stock clutch.
The drum is manufactured from a top secret grade of iron that Scott uses in minimoto racing clutch's
The wall thickness of the drum is 2.5mm giving it enough body to absorb more energy and offer more consistent clutch operation even in the most demanding of engine's and situations.
The system has been designed to work exclusively with the HPI Baja 5B,T and SC running Zen, CY or BZM Micro engines.
We are working on a Losi system as we speak and Dawson 2 strokes are working on BZM 50 compatibility.
The system has been made compatible with the TR H/D gear plate and pinions.
(If you dont have a TR H/D clutch system with a 32mm hole you can cone cut the stock gear plate out to 32mm and use it).
System fully assembled
System fully installed
No need to worry about spares.
All wearing parts are readily available as some parts are very well established on the market.
