If you’re running a LOSI 1/4 scale Promoto-MX motorcycle (like the LOS06000 or LOS06002 models) and want to beef up the suspension, this aluminum upgrade kit is worth checking out. It includes a pair of knuckles and pull rods made from 7075-T6 aluminum – way stronger and more wear-resistant than stock plastic parts. The inner bearings are larger than the originals, which helps the rear shock absorb bumps and landings more smoothly. You get 2 knuckle/pull rod pieces plus 4 bearings (size 4x10x4mm) in the pack. It’s a direct replacement for stock part LOS264001, so installation is pretty straightforward if you’re comfortable working on RC bikes. The red finish looks awesome and gives your bike a custom, high-performance vibe. Perfect for bashing, jumping, or just making your Promoto-MX handle rougher terrain without worrying about parts breaking mid-run. A solid upgrade for serious hobbyists who want durability and better shock response.
