If you own a 2018 Suzuki RM-Z450 this is the one must have aftermarket part of the confused handling machine. The new RM-Z450 has a high rear end that puts a lot of weight on the front. This makes the bike shaky at speed and oversteer. It just feels unbalanced when riding. We tried to band air the issue and drop the sag as low as 115mm, but this made the shock lose travel and some of its performance. Right away we knew what could cure the issue, so we called up Pro Circuit’s Bones Bacon to remedy it.
The fix is a longer linkage arm to drop the rear of the bike and stiffen up the initial linkage curve improving the geometry of the chassis. Now you have the rear dropped without losing precious travel. We helped developed all different sizes with Bones to ensure the perfect length.
These Pro Circuit linkage arms are CNC-machined from billet aluminum. Each link arm includes all of the required bearings and seals. They will be available soon at www.procircuit.com or call (951) 738-8050 to place an order.
