Adjustable Rear Shock 450# & Front Fork Springs – KLX140 R & L

TBparts Heavy Duty suspension kit for the Kawasaki KLX140. If you need to stiffen up the suspension of your KLX140 this is one of the best kits you will find. It will increases the spring rate of the front forks and rear shock so you can push the limits of your KLX140. This kit includes our rear shock that has adjustable rebound and compression, better suited for dialing in your needs at the local mini MX track. We use this with the 14” and 16” rear wheel R/L models.

Rear Shock, DNM – Fully Adjustable

TBparts adjustable rear shock for the Kawasaki KLX140! We worked with DNM to make a rear shock geared toward racing on an MX track! First our shock uses a heavy 450# spring. This gives you the base to stiffen up your suspension and push it harder and further! Next is the adjustability of compression and rebound. This works much better than the OEM shock and allows you to dial the shock in to your exact preferences and needs with just a few clicks. The stroke of this shock is also longer (At least 14mm from what we measured) giving you more travel at the rear wheel!

Once installed your KLX140 will be much better suited for MX applications. This will work with all models, but we recommend you at least have HD fork springs if you use this rear shock (Front fork Springs are very soft). This rear shock offers huge value and performance compared to an OEM KLX140L shock that goes for $350+ !

Installation Note – Please inspect your OEM shock bolts, linkage bolts, and bushings/bearings. If they are worn or bent your suspension will not function properly and it will cause excessive wear. Also be sure all linkage bolts stay torqued to spec. These are common issues we see that can easily be avoided, they ensure a smooth feel and long life out of your rear shock.

Fork Spring Set, Heavy Duty

TBparts Heavy Duty Fork Spring set for the Kawasaki KLX140 R & L! These are approximately 55% stiffer than the factory springs. They are also over 7″ longer, deleting the need for the OEM fork Spring Spacer. These work great for adult riders, they are almost a must as the stock springs are very small and weak.

Installation note – Do not reuse the OEM fork spring spacer.
