In this report I will briefly familiarize you with the initial products (o.e.) Kawasaki/Suzuki 65cc suspension design, tuning ideas, and modifications. As a suspension tuner and motocross hobbyist I have observed a whole lot of discussion about o.e. KX/RM65 suspension. There are numerous concept boards filled with ambiguous suspension modifications and specs for this motorcycle.

The front forks on the KX/RM65 are outdated by numerous decades but can be adjusted for certain using conditions. Damper rod forks as identified on KX/RM65s are outdated considering the fact that they create an overly progressive dampening curve (they are much too smooth in the beginning and as well severe for the duration of speedy fork movement). The rebound adjuster on the front forks can be made use of to alter for some instances of head shake and cornering problems. Head shake may perhaps manifest it can owing to far too substantially or to small rebound dampening. This may be fastened by turning the adjuster in increments of two clicks and take a look at. The rebound adjustment can also aid with cornering complications. If the bicycle washes out in corners, turn the rebound adjuster clockwise in increments of two clicks. If the bike does not stand back again up from corners rapidly ample, transform the rebound adjuster out in increments of two clicks. The front of the bicycle can also be decreased by moving the forks up in the triple clamps. This may possibly assist in cornering but can lead to head shake.

The KX/RM65 designs are geared up with a rebuildable rear shock that is mounted to a present day linkage program. This system raises the shocks get the job done load as the rear suspension compresses further to bottoming. A commencing issue to modifying the rear shock is to established race sag at 70-75mm but to not exceed static sag by 25mm. If conference the two conditions is not possible, a various rate shock spring may well be desired. The rebound adjuster can assist rear stop balance and traction. If the rear of the bicycle swaps to the sides or kicks up it may possibly be thanks to too much or deficiency of rebound dampening. To resolve this flip the rebound adjuster in increments of one particular convert and check. Rear traction is generally periods misplaced when there is also much rebound dampening and this may perhaps be solved by turning the rebound adjuster counter clockwise a person change.

The o.e. KX/RM65 suspension efficiency does not suffice most aggressive motocross riders. There are two effective popular tuning companies out there for the KX/RM65 forks. An emulator valve can be put in which features a fewer progressive and much more predictable feel to the front end of the bicycle. This mod is marketed as a “bolt on package” but is not efficient if installed in that vogue. Added damper rod modifications are required to tune rebound dampening appropriately. A cartridge program is also accessible for the forks that can be put in immediately after machining of the reduce fork legs. This cartridge technique can be tuned by replacing shims and by way of rebound and compression adjustments. The o.e. KX/RM65 rear shock has a lot of likely and can be tuned by a revalve services. The KX/RM65 suspension could be mediocre initially, but with suitable suspension tuning products and services it can grow to be a quite competitive 65cc grime bicycle.
