SHOCKS FOR SPECIAL TWINSHOCK MOTOCROSS BIKES

We are increasingly being asked to supply shock absorbers for special twinshock motocross bikes. These usually take the form of a monoshock bike converted for twinshocks, or non standard swinging arms being fitted to existing twinshock machines.
 

FOR  FITTING NEW SHOCK ABSORBERS ON ANY BIKE, THE ONUS IS ON THE BIKE OWNER TO ENSURE THAT THERE IS SUFFICIENT CLEARANCE AROUND THE SHOCK ABSORBERS AND SPRINGS, OVER THE FULL TRAVEL OF THE REAR SUSPENSION.      WE ACCEPT NO LIABILITY FOR ANY DAMAGE DONE TO THE SHOCK ABSORBERS BY NOT CHECKING CLEARANCE AS THIS IS COMPLETELY OUT OF OUR CONTROL.  ANY SUCH DAMAGE IS NOT COVERED BY OUR GUARANTEE.
 

THERE SHOULD BE CLEARANCE BETWEEN THE FRAME, SWINGING ARM, AIR BOX, AND EXHAUST SYSTEMS. IT SHOULD BE NOTED THAT BIKES LIKE THE HONDA CR 250 RED ROCKET 1978/79 REQUIRE MODIFICATIONS TO THE TOP SHOCK MOUNTINGS TO CLEAR PIGGYBACK SHOCK BRACKET.
 

A good way of checking for clearance is to fit the shock absorbers without the springs and move the back wheel through it full travel.   The rubber shock mounts can compress by up to 2 mm on bottoming out the suspension and allowance should be made for this.   If in doubt please contact the factory

We also supply the spring separators that locate the Top spring and
Main springs together and act as a guide on the shock absorber body.

These spring separators are made from polyacetal which does not absorb moisture, does not swell and is extremely hard wearing in dirty conditions

Main Springs

It may be necessary to change the spring rate for heavier or lighter riders. Special shocks and springs can be made to order. Please telephone to discuss the details of your order.
