Did this XPR Dual Injector setup with XPRs Vortex Tuned ECU and it made huge improvements. Expect more bottom,mid range, and top end without the feeling loss of power even at over rev. This setup will elevate your riding experiance.
It's really a nice add on to my Y Z
I had Vortex from a CRF 450 so I sent it to XPR (Kris Keefer recommended) to have it remapped to see how their maps compare to the already upgraded maps in the Works Edition 250. I couldn’t believe the difference, especially the Torque 1 map. 5 stars for sure.
High quality piece. Great anodizing. Easy fit. QR code didn’t work on the package for instructions, but if you can change lock-on grips you can install this. Not a high performance part, but added peace of mind in case of over heating. Added bling a plus!
I recently purchased a 2nd injector and vortex remap for my 2025 Husqvarna FC 250. It made a huge difference across the power band! The Husky is very linear and it stayed that way, just more power everywhere. I also noticed more over rev on top. This is much better than just buying a pipe. It was easy to install with clear and concise instructions. I have zero complaints. While not cheap, its still money well spent for noticeable power gains.
The second injector with the vortex is hands down the best upgrade to the yz250f that I have done. I did the 450 air box mod prior to this and it helped with bottom end a little but after switching over to this second injector it is a night and day difference. The second injector completely wakes the bike up. I have mine mapped to run t4 and it is phenomenal. If I had to do it again, I would’ve skipped the 450 airbox mod and gone straight to this.
So much more power! Stop thinking about it and just do it. Totally worth it!
This is the ultimate upgrade for your 250. For those on the fence about purchasing, You will not regret it
How can you not give this 5 ☆. Best aftermarket small part that can make that ride in the back country a pleasant one. Instead of walking the bike back to the truck because Yamaha engineering thought a piece of plastic MM from the exhaust won't get soft and rupture. Thank you XPR for that peace of mind.
Ordered the dual injector and Vortex ECU from XPR. Shipping was super quick. I even emailed asking a few questions when i got it and Leah responded immediately (on a Saturday night literally in the middle of A1). So exceptional service but the injector kit and mapping on the ECU are even better. I'm absolutely amazed at just how much this combo woke up my sons 2025 YZ250F. I can't recommend these guys enough.
I had flame out issues on the KTM 350XCF 2018 model i tried from the start adding a fly wheel weight then after that i added a rekluse clutch i even reflashed the ECU via a reputable local tuner with still no luck! or a result i was looking for so in the end i let the moths out of my wallet and got to the core of the issue and that was installing a xpr mapped Vortex and that nailed it on the head , the bike is insane and pulls like a 16 year with a playboy magazine ! Trust me dont be a tight ass and just buy it ! No flame outs at all !
Fast easy install. Well made.
Well made, easy install. Always need more titanium!
