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.

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.

Throttle response good, bog bad!
I’ve had great luck with these reeds in the past. I just bought a new to me Husky TC250, with a factory Husqvarna 300 conversion kit! I’ve always wanted a 300 and can’t wait to blow out my first berm on it. However, age and the added knowledge that comes with having ridden used bikes for twenty years mad me do the right thing and tear down the entire bike to really get down to brass tacs with this bike. I’m super glad I did as one of the many things I found wrong with the bike was a worn out, stock reed cage. Every single reed had a gap between the cage. Which explained the bog I was getting. None the less, I was not disappointed after installing the V-force 4 reed cage. Throttle response is crisp and clean! They make a great product!

What I hoped for
Replaced my old reed with the Vforce4 and was very pleased. Throttle very crisp easier to start and is now very responsive. Give it a try, you will not be dissapointed

Good quality
Quality, fit and finish are great. Seems like a slightly larger opening than original cage to allow better flow. Installed on a 2016 ktm 250xcw with stock jetting and pro circuit exhaust. Noticed a slight power gain.

Won’t make you push your bike for miles.
Didn’t notice any great performance increase, but after reading horror stories of riders being stranded by OEM reeds I knew these wouldn’t let me down. And so far after two years haven’t had a problem riding most weekends.

Worth Every Penny
I ride an '07 KTM 250 XC setup for gnarly woods riding. The bike came with a VForce 3 reed block and when I cracked one fo the reeds I upgraded to the VForce 4 on the recommendation of my local KTM shop.

Couldn't be happier with it, looking at the picture of the product you'll see the reeds have stoppers/bumpers behind them on this block. That keeps the "flap" within a smaller area and equals faster, crisper throttle response and better bottom end torque.

I paired this up with a 13/52 sprocket set and an 11oz flywheel weight and I can pop the front tire over logs, rocks and root faces at will.

Buy it, you wont regret it.

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
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 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.
