Heavy Hitter 85 MX Fork Conversion Kit

All Gritshift items are drop shipped from Gritshift in Florida. Not available locally!

If you're one of the few riders that wants to push your Sur Ron or Talaria to the absolute limit – far beyond what the stock mountain bike-derived front end can handle – those mountain bike suspension options just aren’t going to cut it.

With robust CNC machined parts delivering optimized geometry, you can now transform your Sur Ron or Talaria with the addition of tried and true KTM capability.

Born of necessity. We designed the Heavy Hitter Big Sender MX fork conversion kit out of necessity. Ask us how many stock Sur Ron and Talaria forks we blew through before we decided to fix the problem. On second thought, don’t ask – we stopped counting after a while. For the kind of riding we do, from hard stunting to hard enduro and everything in between, there’s just no way a mountain bike fork is going to hold up. One night we looked across the shop and saw a perfectly good KTM 85 sitting there, and one thing led to another, and the Big Sender kit was born soon after.

True KTM quality. We found the 85cc KTM platforms are sprung very accurately for the weight of Sur Rons and Talarias, especially factoring in the added weight of an upgraded bike. If you’re at this point in your build, you have probably added about 20 pounds to your bike already from a bigger battery and additional accessories, and the Big Sender kit is the icing on the cake.

Fix all your problems. Not only does this kit let you tack on a far more robust set of forks, you can also dial in your settings in ways MTB forks cannot. You can now run your choice of KTM 85 MX forks and a wider variety of front wheels, and the short service intervals of the OEM front forks are eliminated. All you need is this kit and a complete KTM 85 MX front end (explained below).

Robust construction. The Big Sender kit consists of billet aluminum bearing cups, pre-pressed bearing races, and a durable black anodized finish on external components. We beat the absolute heck out of this setup before bringing it to market so you don’t have to worry while you’re going full send.

Features

• Take your e-bike into another level of capability with the Heavy Hitter Big Sender kit
• Convert your e-bike to run real MX forks from a KTM 85
• Eliminate weak failure points and short service intervals of OEM front end
• Gain the ability to dial in settings for your weight and riding style
• Pre-pressed bearing races for simple install

 

Technical Notes

A complete KTM 85 MX front end is required. This usually ranges from $799 to $2,599. A complete front end consists of fork tubes, triple clamps, front braking system, front wheel (19" recommended), front axle, and MX style handlebars. Price is largely dependent on which fork style you choose: Dual cartridge spring forks are heavier but cheaper, whereas air forks found on 2018+ models are lighter but more expensive. From our experience, we would choose air forks every time.

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.
