Details

    The unique design of the V-Force reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact, sheds light on another V-Force advantage. Since the petals are only traveling half the distance, they generally last longer are they receive less wear than the reed petals on a conventional reed valve design.
  • Reed petal resin system, carbon fiber and lay-up.
  • Pre-curved reed petal ensures better seal at tip.
  • Wider reed cage for maximum airflow.
  • Combined reed tip area increased by 10.5% resulting in increased total air flow.
  • Airfoil shape added to cage tip to increase air velocity from outer ports.
  • Long reed stops added to progressively slow petal tip velocity, for increased petal durability.
  • Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape.

great add
These were stock on older KTM/Husky's and I always thought they worked excellent so when I got a new Husky and it did not have these I installed them and they did a great service to the entire power band!

Top notch reeds!!
I was starting to have issues caused by OEM reeds on my '14 KTN 300XC so I got these. As expected product performs very well and delivery was quick.

Replacement for new 2018 Husky TE300
Unbelievable...I was hesitant about installing this on my brand new bike because i thought there wouldn't be much of a difference....i was wrong, oh so wrong.

The amount of power i gained is insane. I've gained a lot of low end power, to a point where i needed to tone down my red power valve spring. I've always been a power junkie and always want more, but having the bike lift just from a quarter throttle is not fun in the woods.

Very clean low end, smooth transition into the mid but not much top end which is fine. I'm so glad i made this purchase, night and day difference.

Bolted Right on, No adjustment Necessary
Stock OEM reed petals busted off after 20 hours on my new bike. Bought these to replace and they fit and bolted right on and didn't even have to make any adjustments to the carb for it to run well.

Does this come with one or both of them?
Erik B on Aug 1, 2017
BEST ANSWER: If this is for a Banshee, it will include two Reed Valves. One for each intake.
With this upgrade, would I have to rejet the bike?
Jorge G on Aug 27, 2017
BEST ANSWER: Most likely I would say no. If you put it on and like the way it runs than no. You may have to adjust idle screw. I usually use JD kits in my bikes, although sometimes I use the stock needle, but I run aftermarket pipes and I've been riding 10plus years. It all depends where you are riding (altitude and temp) and how you ride...amount of throttle and what kind of response you are looking for. Feel free to ask other local riders (preferably vets) and see their take but opinions are well...opinions
Does this reed valve also come with the rubber boot that connects it to the carb?
Jacob P on Jun 10, 2019
BEST ANSWER: Hello Jacob, while it all depends on application I am almost certain it does not. Have personally bought two for ktm’s, for a 08 250 and 18 300 and they do not come with the carb connection. The only listed versions of the V4 that come with a boot are for Yamaha 65/85 and Suzuki 85, according to manufactures listings. Hope this helps. Cheers.
2017 ktm 300 xc-w six days? looking to replace stock reeds before its a problem in the hills any info will help thanks
RON M on Apr 8, 2017
BEST ANSWER: I would pull your stock reed cage out and check for gaps. There is a known issue with the 2017s and bad reed cages. I have a 2017 300xc and there were several large gaps in my stock reed cage. This new vforce4R not only solves this issue but the throttle response is very crisp and responsive.
Does this reed cage include a new gasket?
Tad M on Jun 24, 2018
BEST ANSWER: I wasn't 100% sure since I have had mine on a couple years so I went and opened the box. Per the instructions it says it has the supplied gaskets. Hope that helps.
Will I regret switching this for my stock reeds if I ride a lot of technical low power stuff?
"2016 Ktm 300 xcw"
A shopper on Nov 26, 2019
BEST ANSWER: I made the switch pretty seemlessly on my ktm 250sx that I ride mostly technical mountain single track in the kootenays, really didn't notice a huge difference really from stock
Will this part fit a 2017 TC250?
kevin c on Aug 28, 2017
BEST ANSWER: The 2017 TC has a different reed valve than the 2016 and older. This part will not work with the 2017.
