***2026-2027 WP AER 35 Forks***

We are really excited to have AMA Limited Class legal spring conversion kits in stock for the new style forks on all KTM, Husky and GasGas 50 and 65 bikes. WP updated the forks in 2026 and there hasn't been quality spring conversion options available. We now have them, ready to install. We offer them along with custom spring rates, revalve and also a ProValve option. The improvement to these forks is drastic with this setup. Thanks to Krooztune for being willing to build these to meet AMA requirements. We have used their products for several years now and the quality can't be beat.

This was an interesting one.... disassembled a Cobra shock and this is exactly how it came off the shaft. Who knows what is wrong with this picture? Hint, it had some fast rebound....

Dang weather.....

we are canceling practice for SATURDAY BUT race status will be updated Saturday FOR Sunday race. we want to provide the series with the needed race for tmxa championship series so we’re keeping our fingers crossed the hurricane effects will push east. 2026 weather has not been good for Back40mx so we appreciate your patience as we see what comes our way. Prayers go out to the folks in the south that will be greatly affected by the storm in more serious forms than a race. BE SAFE!!

Fresh '27 PW Built and headed to Ponca! We've been busy building a bunch of Cobra's the last couple of months but there has been a wave of PWs this last week. We are here for all of your 50cc-85cc needs.

We managed to get our hands on a couple of 2027 PW's. 1 is being built for Ponca but we have 1 available if anybody needs 1. They are hard to find right now so call or send a message to grab it.

4 weeks until Ponca. There is still time to get dialed in before it gets here. If you need your Cobra Engine built, a suspension revalve or service, a PW build, KTM 50 or 65 engines or suspension, call us or send us a message to get on the schedule quick. It will be here soon.

We will be at Acen's MX this weekend if anyone needs any 50, 65, or 85 tuning. We will be available to check your CFD, set sag and help with suspension settings, and help you tune your PW if needed. Feel free to stop by our tent if you need anything.

We've been hard at work building engines and testing fuel setups getting ready for Loretta Lynn MX next week. We may not have the most bikes on the line, but you can bet we have been putting in the work to give our riders the best possible bike on the line. We are ready for a solid week at the ranch!
