This is our billet 40% gear reduction for the Honda Foreman 400/450. Internal case clearance/cutting needed for install. Our stiffer clutch springs are recommended for this reduction and can be found in the "400/450 Foreman" and "Parts" section of the site listed as "TRX Springs".
**ES models will need a shift module to prevent electronic shift issues, also located in the parts section.
All of our primary reductions carry a limited lifetime warranty to the original purchaser. (See disclaimer on home page) We've been making Honda reductions for over 10 years now utilizing our 20+ years of machining and metal-working experience.
All reduction orders come with a free t-shirt! Please include your shirt size in the notes of your order (M, L, XL or 2XL). To purchase additional shirts use the link below.
