JMC Swingarm Logo
ALUMINUM SWINGARMS

JMC Aluminum Swingarms are hand-made in England of 7020 Aircraft grade Alloy. That is the highest quality and strongest weldable alloy available for any price. They can easily handle the torque requirements of the hottest street engines of any size. Besides giving your bike a very "Trick" appearence, and lowering or raising capabilities, you will immediately enjoy improved ride and handling because of the low un-sprung weight and ridgidity of the swingarm. These swingarm's can take off as much as 21 pounds of your bike's weight. That's like getting 2-3 more Horsepower for free!

Eccentric  Axle Adjuster Standard

ECCENTRIC ADJUSTER
Standard on all our JMC swingarms.
JMC Eccentric adjusters will make a difference to the ride height of the Motorcycle by a maximum of 16mm from the standard position,many people are rather paranoid about this thinking that this will influence the handling. In fact it can be an advantage as you may adjust the ride height to your preference. The ride height adjustment may generally be either above the 3 to 9 oclock position or below this. There are a few bikes that require the adjustmentt to be either above or below due to restrictions on rear brake caliper,or chain fouling the swingarm. In these cases adjustment must be made in a direction that eliminates this. For purposes of adjustment a purpose made tool is available.

Axle Adjuster
SPECIAL ORDER

This Type of Adjuster is favoured for use where an increase in wheelbase may be required for Drag racing/Sports events, the forward most position is the same as the forward most position on the standard swingarm but then has the advantage of 115mm (over 4 -1/2") of further adjustment. Wheel adjustment is carried out by loosening large Nyloc nut then turning 8mm bolt (clockwise) to lengthen wheelbase or (anticlockwise) to shorten wheelbase. As can be seen the ajuster bolt remains inside the ajuster housing in all positions so does not leave an unsightly bolt protruding from the back of the swingarm . If more than 115mm of arm extension is required this can be accomplished by requesting the arm to be made longer.
