Designed from the ground up, XPR manual cam chain tensioners help reduce friction and drag, giving your engine more horsepower with a freer feeling, quicker revving response. The stock cam chain tensioner puts excessive tension on the cam chain guide, creating a lot of drag and heat which reduces horsepower and response. With our recommended adjustments, our manual cam chain tensioner allows you to set the tension for optimal performance.
Features include:
- 2 titanium bolts and a titanium nut, for longevity with less weight.
- Strong and lightweight billet aluminum body.
- Hard-anodized coating for a durable finish.

Over all the years that I have been riding / racing I have tried many companies and products. As a vet rider / racer I can absolutely say that XPR Motorsports is by far the best place to deal with, their customer service is bar none, the quality of their products is fantastic. I recently purchased a 2nd injector kit with Vortex ECU for my 2025 Yamaha YZ250F and am thoroughly satisfied. Chad and Leah took the time to explain and answer all my questions, I love the fact that they care about their customers satisfaction. I will be a lifetime customer and absoluetly recommend them.
I have done a lot of research on ECUs and how they change the bike. This ECU has brought my bike to life in a way I did not know was possible. It almost feels like a 350 now!! The low-end map in the sand works phenomenally. It’s almost like being able to go up one tooth in the rear sprocket by a map! Then, the all-around best power map made my chassis feel much more compliant, and the power was consistent throughout the throttle range. This ECU helps your bike’s power, suspension, and chassis feel. Trust me. It's worth every penny!
Sent my Vortex to Chad to get some more top end power and over rev out of my CRF250. Absolutely knocked it out of the park in meeting my needs with this bike. A+ and highly recommend! Communication is the best in the industry as well!
Couldn’t be happier with the quality of product. Super easy installation!👍
Our new race bike got the 2nd injector kit and Vortex X10. It truly changed the bikes overall performance and power delivery. We also tested the Vortex on the single injector and it was night and day difference. For those looking to have single injector but more gain then the Vortex X10 is the way to go. Set aside from the kit, customer service was fantastic and had answers to all of our questions. We are very impressed with the results from both XPRs services and quality!!!
Installed the XPR mapped vortex with an FMF full exhaust system. The combination made noticeable improvements. The bike now revs quicker with a slightly better mid-range and much needed improvement to the top-end.
Had to buy it due to the PC system being bigger, and hotter than stock. Super easy to replace. Took less than 10min even with draining and refilling the coolant.
Vortex ecu with xpr maps and cut air box = whole new bike ! Way more torque, more midrange , it will pull 3rd with stock gearing with a stock exhaust , on pump gas I can only imagine what a muffler and race fuel will do , if your not sure to pull the trigger on a vortex from Chad quite thinking and do it !
Bought a vortex and definitely well worth the money! Very satisfied with tunes and overall purchase. Had some questions and Chad is full of knowledge and great with his customers highly highly recommend!
This thing rips now! Excellent customer service and response with any questions I had.
