If you're one of the few riders that decided the Sur Ron and Talaria Platforms can't support Mountain Bike suspension and have blown through multiple forks at thousands of dollars then this kit is for you!


Introducing the Heavy Hitter Big Sender Fork conversion Kits for SurRon and Talaria. 

This Kit features billet Aluminum Bearing cups designed for a seamless installation of your choice of 85cc MX suspension. The 85cc platforms are sprung very accurately for the weight of the Sur-Ron and Talaria including the weight of an upgraded bike, usually adding 20 lbs. to your bike from bigger batteries and additional accessories. This also gives you the ability to dial in your sag settings, and have your forks properly built for your weight and riding style.


A complete MX front end is required, which usually ranges from $799-$2,599. Depending on the fork type you decide to go with (Dual cartridge spring fork KTM "heavier but cheaper") or air forks 2018+ KTM (Lightweight but a little more expensive). A complete front end consists of, fork tubes, triple clamps, front braking system, front wheel (19" recommended), front axle, MX style handlebars,


Note: For KTM Air Forks please check clearances on the bottom for the 2 posts on the triple clamp where the fender bolts in. This may need to be slightly shaved for adequate clearance and is only an issue with some years and brands of triple clamps.
