State of the art technology!
These fantastic HAASE Low friction Sprockets are now available in the UK!
For all modern trials machines including: Beta, Montesa, Sherco, Gas Gas, Scorpa, Vertigo, TRS, Ossa & Jotagas, with standard 4 bolt hub fitting, To be used with a 520 pitch chain.
The reduced number of teeth means reduced friction on the drive chain, Which the loss of friction is transferred into torque to the rear wheel.
Advantages over a standard sprocket:
* Reduced friction on the drive chain.
*Increase in rear wheel torque, Providing more progressive & smoother power delivery
*Increased freewheeling effect
*Reduced wear on the drive chain
*Solid machined design to match the FIM Regulations and other National events, No need for a sticker to cover it up!
*CNC machined from highest quality AW-7022 grade billet aluminium
*Extremely lightweight.
They have been thoroughly tested & used for many years with excellent results and used by many pro riders including Czech Republic Trials champion Martin Matejicek, 125cc British & European champion & 2018 Trial 2 runner up Toby Martyn & Victory Yamaha factory racing trial team
They also are original equipment on the Electric Motion 5.7 Sport, Please see the images.
The spacing of the teeth have been specially designed so it doesn't allow the chain to jump, So it is in full contact with the sprocket at all times.
Recommended fitting with new or nearly new chain and new front sprocket for equal wear
This listing is for the equivalent to a 48T sprocket.
Must be tried! These really are a big improvement to a standard sprocket!
