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.
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
These are a huge plus to my machine, im on an 08 250xc ktm and it came stock with vforce 3 reess which were nice till they started fallinf apart and i got the 4's and they woke my bike right up
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.
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.
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.
I noticed an immediate improvement over stock in power across the whole RPM range. Increased throttle smoothness and predictability while drastically improving the top-end. Didn't need to rejet because the bike was already rich in stock form. A+ , love it. Comes with the required gasket.
I have a 07ktm300 that come stock with the vforce3. I just changed it
To the vforce4 and noticed the differenc immediatly
This bike is alive now.it feels a lot more radical andd zappy
There is little a person can do in order to make your dirt bike more powerful. This is one thing and therefore it is a must have. All aftermarket reeds are noticeably better and this one is top of the line. The biggest difference is the crisp; snappy power. Be sure your pilot jet is lean enough so you don't get a bog delaying the power band...this may give you the impression the reeds didn't improve anything. PS: too lean and the bike will bog at full throttle.
Had the 3's stock on my 250sx. had a petal chip so went with the 4's.
throttle feels crisper and bottom end seems to be smoother.
Bike feels overall snappier mid range.
Nice upgrade if you are due for some reeds
I put a VForce4 on my KTM 300 EXC. I had to order some SX-based parts from my dealer in order to mount it, but after I got those, it was pretty straight forward. The instructions should mention this basic fact. It tells you to hack-saw off some rubber boot, but the EXC comes with an all metal piece which simply must be thrown out and replaced.
After I got the part on, my EXC is alot better. It pulls harder everywhere and has better high rev carboration. I like it alot!
