Spring time is in full swing here at ProCycle. With these busy days please be sure to let us know if your order is time sensitive. We try to do as much as we can to accommodate your upcoming trip.
In 2008 Yamaha discontinued the XT225 & re-introduced the XT250. Powering the XT250 is a 249cc, air cooled, SOHC, single cylinder engine. Helping drive the XT250 is a five speed transmission & wet multi-disk clutch. In 2013 the US version XT250 gained fuel injection.

Included in this kit are .42 kg/mm fork springs, Cogent DDC (Drop in Damper Cartridge) performance cartridges and two bottles of 5w fork oil.
These springs are custom wound specifically for the XT250. Stiffer than the stock springs, these will make your front perform significantly better. Combine them with the Cogent DDC's and you will be very happy with the results. Sold as pairs .42 kg/mm.
These Cogent Drop-in Dynamic Cartridges will vastly improve both the compression and rebound damping of your stock forks. No disassembly of your forks, no drilling of damper rods. Just change the oil to 5w and install the DDCs under the springs and hit the trails.
Stiffer fork springs are required to realize the full benefits of the DDCs. Please call if you have any further questions.
The DDCs are not recommended for use with progressive springs.
The DDC Install/Removal Tool which makes installation that much easier.
Damping rod forks are notorious for being both too harsh yet too easy to bottom. This is the nature of damping rod fixed orifice forks.
Cartridge Emulators make damping rod style forks perform like well-tuned cartridge forks. These tunable valves sit on top of the damping rods and are held in place by the main springs. This makes them both simple to install and completely tunable for all conditions and rider preferences.
Genuine Yamaha fork seals and dust wipers.
Add a fresh set of inner and outer bushings for a complete fork restore.
High quality fork boots. Sold in Pairs.
Choose from; black, red, royal blue, yellow, or light blue.
Helps protect vulnerable fork tube and seal from dust, dirt, and corrosive elements. Hook & loop (Velcro) fastening on back side makes installation or removal for cleaning a breeze.
The Modoc 250 replacement rear shock significantly upgrades your Yamaha XT250 suspension. Cogent Dynamics custom build this high quality and high performance shock custom to suit your riding needs.
Cogent Dynamics build a fully custom suspension component, just for you. To best meet your needs, please spend a few moments providing us with your riding style (off-road / adventure, or street / commuting) and your approximate weight with gear and luggage in the comments during checkout. The information you provide helps them setup your suspension to most closely meet your needs.
Specifications for the Modoc 250:
Race Tech HP Springs have a high stiffness-to-mass ratio. In other words; the springs are light weight for their particular spring rate. This requires the finest materials and processing. Shot-peened and pre-set so they cannot sack out. All Race Tech HP Springs have the highest rate tolerances in the industry. These are the finest springs in the world-guaranteed.
OEM spring rate is 6.7kg/mm. We offer stiffer spring rates for riders who wish to carry luggage or just prefer stiffer suspension.
Race Tech shock springs require adapter collars which are included with your spring. *Spring color may vary due to specification requirement and availability.

8.0 kg/mm is 24% stiffer than stock
Stock suspension suffers from poor compression damping and limp rebound damping. The Race Tech Gold Valve allows you to tune both compression and rebound valving for vastly improved performance.

Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.
The three forces of suspension, testing procedures, even the black arts of chassis geometry: Thede explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.
Use this installation tool from Cogent to be sure that your Cogent Drop-in Dynamic Cartridges are installed correctly. A strong magnet in the end holds the cartridge firmly while you lower it into your fork leg. Then slide the spring over the tool until it holds the DDC down, then gently remove the tool. That simple. Never again question if it is properly seated on the damper rod.
Works equally well for removal when you need to change your fork oil. Also works great with Race Tech Emulators.
Innovative design makes tool easier and more secure to use than old fashioned pin-aligned drivers
Showa removed the schrader valve on many newer rear shocks. Now you need a needle to recharge your shock with nitrogen after a rebuild. Race Tech built this unit just for that job.
The features of this tool include 300 psi capacity, bleeder valve and T-handle plunger pin chuck. Swivel chuck has a 12" flexible hose. Comes complete with instructions, carrying box and Schrader valve extension (required on some Showa shocks). Nitrogen bottles available at any welding supply house.
Makes installation of your linkage bearings much easier. Also simplifies maintenance of those bearings.
