We see Kawasaki has added a 2014 “New Edition” KLR650 with revised springs and rebound damping at both ends, and some mods to the seat (and we will try to get some feedback on it ASAP). However, here at Top Gun, we’ve had a selection of KLR-specific springs available for several years (and the original 6.6 kg/mm spring going back almost 10 years!).

Even a preload setting of “5” on the stock shock/spring will not carry the average rider with gear at the correct ride height, which thereby reduces usable suspension travel. This will result in excessive bottoming of the rear suspension over rough terrain which in turn will create excessive chain slack and chain contact with the bottom of the air box.

Our Top Gun Chain Master can solve the latter problem, but without a proper spring, you can’t get back that lost suspension travel.The only way to properly set your ride height is with a spring chosen to match your intended riding load. You can try to compensate for a weak spring by cranking in excessive preload or by installing “raising links”. However, while these methods may address the symptom, they don’t cure the problem – and each comes with further disadvantages when compared to a proper spring.Excessive preload settings can result in inadequate static sag, leaving you without enough suspension extension to keep the rear wheel in contact with the ground over holes and hollows. This leads to a rough ride as the wheel then impacts the ground instead of smoothly stroking up and down with the terrain.Raising links allow the rear end to start higher than stock links, the idea being that when the rear end still sags excessively, the higher starting point will allow the bike to settle at a reasonable ride height. However, you’ve still used up more suspension travel to get to that position than the same rider would with stock links and a proper rate spring. Additionally, when the suspension unloads, the resulting higher rear end will create twitchier steering since the rake and trail will be lower than stock values. Only a properly sized spring can put you at the correct ride height and adequate suspension travel without the disadvantages mentioned above.The Top Gun springs are made with the highest quality materials by an experienced and well-respected firm. The springs are custom designed for the KLR, both for ease of installation and functionality. By offering three springs, we can cover the vast majority of riders. The table below shows the recommended spring by rider/load: 

Model Year
Stock Spring
6.6 kg Top Gun
7.4 kg Top Gun
8.0 kg Top Gun
1987-2007 Less than 160 lbs 161 lbs – 230 lbs 231 lbs – 280 lbs 281 lbs – 330 lbs
2008 Less than 180 lbs 181 lbs – 250 lbs 251 lbs – 300 lbs 301 lbs – 350 lbs
 **All weights are inclusive of rider, riding gear, and load carried. All weights listed are
estimates and may not be optimum for all rider seating positions, load distributions, rider
preference, or suspension modifications. Differences in weights for 2008 model are due to
redesigned Uni-Trak lever and suspension links.**
These are straight-wound springs, not progressive springs. We purposely chose a straight-wound design to complement the rising-rate suspension characteristics of the KLR650. The KLR Uni-Trak Lever is designed to provide a cushy ride during initial rear wheel travel, but progressively stiffen as the suspension nears full compression. Adding a progressive spring (which has its own rising-rate) can cause a rougher ride than necessary, and even lock out the last few inches of wheel travel because of the high forces required to fully compress the spring.
