Ypvforce reed valve system

2017 KTM 300 has reed issues. I replaced them w/ this and I know I won’t have any problems anymore. I can’t compare performance because I didn’t run the OEM reed system I have these on my other 2-t machines and they are great. They really made my 09 KTM 300 sing.

Great descriptions

I bought this reed cage and waited a couple weeks to install it, mistake! I noticed instant improvement in throttle response and power from low to high end. Great product.

V-force 4

I noticed a reed chipped during some maintenance. I compared prices to change reeds or upgrade from the v-force 3 to the 4. A quick internet search showed a lot of positive feedback for the v-force 4. I spent the extra money, and I'm very happy w/ the overall results. Now obviously my bike's reeds needed help, but the bike felt really strong w/ more torque then I ever remembered. Too new to comment on durability, but my v-force 3 lasted a very long time, so I expect this model to at least last as long, if not longer. Bike is a '09 KTM 300xc.

2009 300XCW - Power and Torque is Back

My stock reeds blew. Iwanted to just buy new reeds but I wasn't sure if they were going to ship me V-Force 3 reeds or V-Force 4 reeds. So I just bought a whole V-Force 4 cage assembly. I'm happy with the new cage & reeds and I think the design is better than old version. I think it was worth buying the whole cage.

Prior to my reeds blowing, I thought my rings or piston needed to be replaced because my bike was starting to feel sluggish when going up hills. After replacing the reeds I feel like I have the same amount of Power and Torque as when I first bought the bike.

Big difference in power from bottom to the top had to go from a 172 to a 175 main jet to make it perfect

Wake up call

Installed the Vforce 4 on my 15 KTM 250sx and wow! The snap and crisp throttle response the reed offers is amazing. I paired it up with PC pipe & silencer and they complement Eachother well. The Vforce fills in the gaps and and adds a crisp quick snappy power delivery.

2016 300 XC-W

Awesome product, if you can use a spoon you can install this. With stock jetting at sea level and 45 degrees the bike was lean in the mid-top. After fattening up the main and lifting the clip on the needle it was a rocketship. Incredibly noticeable increase in throttle response and pull from idle to top. Highly recommend. Currently running 35 pilot, 175 main, clip in 2nd spot, N8RG needle at sea level 35-55 Fahrenheit with FMF Stealth Q.

Faster bike

Ever since I bought my new 2015 KTM 300XC it felt like something was missing. It felt sluggish to me from previous KTM 300's I had. Once I put this VForce on the bike the sluggishness went away and the bike is now fast. I would recommend this to anyone who wants more speed from their bike.

Q: Are the VForce 4 reeds also compatible with the EU version of the 2016 KTM 300? Which is the 2016 KTM 300 EXC
1 year 4 months ago
I'm a long time user of the Moto Tassinari's VForce 3 reed valves, i've used their product in my past 3 bikes (2 Huskys and 1 KTM 125 EXC) and haven't had any problems with them, only great experiences! Now i've came into the age of buying a 2016 KTM 300 EXC from my friend and i was wondering does this VForce 4 reed valve system also work the 300 EXC (the EU model of the KTM 300 2 stroke enduro bike) or are these only compatible with the XC and XCW (the US models) ?

When will you be stocking the vforce 4's for the '17's? It is a huge issue on the new bikes, so hopefully you will be stocking them soon.
