Important Notice: When installing, make sure your chain tension is not tight! Any chain drive that you install should have loose chain tension! Please check the fitment tab for important motor info.

The Heavy Hitter Primary Drive Conversion Kit was designed for those wide-open throttle riders who just keep snapping belts. Why the Heavy Hitter kit is the best? Replacing a belt drive with a chain drive will lower the bike's efficiency, which in turn affects power delivery.

Chain drives are stronger, just not as efficient. Heavy Hitter's goal with this chain drive is to give you maximum performance by providing the lightest kit on the market! The primary chain drive sprockets are machined from 7075 T6 billet aluminum and have been put through the hardening process with the anodized black finish.

This kit comes with a high-quality o-ring chain to offer the longest lifespan. If you want your primary drive to perform even better you can use a standard non-o-ring chain, however, the lifespan of non-o-ring chains will be shorter. The provided o-ring chain is equipped with a master link, facilitating straightforward replacement without necessitating the disassembly of the swing arm.

NOTE: This conversion kit maintains your bike's original gear ratio, and OEM motor alignment. Your bike's fitment will be labeled on the motor sprocket and should always face outwards! 
-Aluminum sprockets always have a shorter lifespan than steel sprockets. The purpose of this kit is to offer maximum performance

Amazing fit, great quality material
Size: 30W x 32L, Color: Medium Grey, Size: 30W x 32L, Color: Medium Grey
I ordered this pair of denim pants in my usual size (30x32) and they fit amazingly. The cut is slim, but not overly tight. The material is the perfect thickness and seems to be of excellent quality, with a slight stretchiness to it. They are slightly softer than most denim pants I have worn. I am finding that they are great for both business casual settings with a button-up shirt and more informal "dress down" type situations with a t-shirt and sneakers. This is probably my favorite pair of jeans that I have gotten in at least a few years, and I would highly recommend overall.

Soft, comfortable fitting jeans
Size: 30W x 30L, Color: Black Rinse
Good quality and a great slim fit, but a bit expensive for a blend. Since they aren’t 100% cotton, they have a slight stretch that makes them more comfortable and softer than standard jeans. I’m happy with the look and feel, but I’ll have to see how they hold up over time.
