Best Shock and Suspension Parts

"My suspension seems pretty good, what do I need to do?" Or "My suspension isn't too bad, should I do anything with it"? The issue is that until someone rides a bike with superb suspension, they just don't know the difference between "seems pretty good" and "this stuff is awesome!". Most people that are past the novice stage of riding are held back by their stock or near stock suspension. They just don't know how good it can be, so they struggle along wondering why they can't hit that line, why the front end deflects on everything it hits, why the bike is harsh and dances around in the rough stuff, but will bottom on jumps. What we have achieved with KTM/WP suspension is really, really good, affordable, and directly addresses the WP harshness, front deflection, blowing through the stroke front and rear, bottoming, front wheel push, and keeps the tires on the ground in hack and in corners like they were velcro'ed there. No one puts in the kind of time and effort we do on KTM/WP suspension, and it shows in the quality of our work and the suspension performance we have achieved with KTM's. We know our constant R&D with KTM’s helps us to give you the very best KTM suspension available, we are very confident you will love it, and we guarantee your satisfaction. Although 99% of our customers find their upgraded suspension to be remarkably better than stock as soon as they try it, sometimes we have to help with clicker adjustments or tweak things a bit to make it work for different riding styles and terrain. We will work with you until your suspension works for you. You have a full 60 days with your new suspension to play with your clickers, get it dialed in, and even send it back to us for free internal tweaks if needed. If you are not happy, just return the suspension to us within 60 days, and we will return it to stock and refund 100% of the parts and labor cost for the suspension upgrades. (PLEASE NOTE: Repair parts, like seals, bushings or damaged parts that were needed to complete your suspension work are not refundable). 

We have thousands of hours of research and development time spent on our suspension dyno and on the track, far more than anyone else has with KTM. When we hit a performance brick wall, we try everything to get around it, even crazy "outside the box" stuff, and when nothing works well enough to satisfy us, we identify the root cause of the problem, and make a prototype part to fix the problem. Often that means 30+ prototypes for a single part, to make sure we had it as good as it could be. I don't think anyone has gone to the extremes we have with R&D on WP suspension. We even hired a thermography expert to come set up his equipment so we could see exactly where heat is generated in the WP shock, how much, where it collects, and how well our reservoir designs were getting rid of it. Many prototypes are machined and thoroughly tested both on our suspension dyno and on the bike before we settle on the final design for any of our suspension products. We developed the shock and fork pistons because we could not get past some tuning issues with the stock pistons, no matter what valving we tried. We spent hundreds of hours on R&D developing our pistons, both seat of the pants testing and dyno testing. On the shock alone we went through 36 prototypes before we felt we had the best design combination of flow dynamics, low turbulence/cavitation, tuning range, and most importantly, what WORKED in a race. The reservoir was tested in 4 different sizes with 2 different fin designs and 3 different bladder shapes, 24 configurations total, to arrive at the best combination of function and heat dissipation.
