· The design of the VFORVE 3 reed valve system features double the intake surface area over standard reed valves, giving Increased overall mid range, top end power. Greater efficiency and reduced reed petal wear due to reduced reed petal travel.
I bought a pair of Delta V-Force 4 for my 34 year old Yamaha RZ 350.They rip, very crisp throttle response and great top end. The build quality is beautiful. Very happy with the purchase:)
Everything seems good. Not sure if they are knock offs or not but if they are they fooled me. Fits perfect and looks great. Undeniable performance increase as well. I'd put these on anything and not think twice.
Great product , great design , way better than the 3s. I upgraded to billet Intakes at the same time and I love the snappy throttle response and extra power.
Fit was great! Worked like it was intended. Packaged well and shipped fast! I'm very pleased with this product! Would definitely recommend to a friend!
put in my Yamaha banshee 2 into 1carb totally different bike runs cooler and smoother wakes the banshee up .its a must have for banshee owners 5 stars plus product
I had boyesen superstock reed pedals and switched to these. So much more crispy throttle response. Made it better all around the power. Worth the money
