My son has a mini bike with a predator engine and this worked perfectly for his mini bike it came with everything we needed! The quality is great and durable and easy to install.

This will be the first of three chain roller fitment reviews on my vintage (1988) off-road motorcycle. Images show differences between a factory suggested replacement, (plastic) vs. that of this wider, all-metal chain roller. Like the OEM model, this roller came fitted with two sealed bearings that desperately needed grease. Applying a medium viscosity lubricant greatly improved free spin and eliminated excessive drag. By design, this roller functions best used as a tensioner. As such, it will be mounted in the lower swingarm position. In summary, the roller fit, finish, abundant hardware and ease of installation make this a great value.

Fits my doodlebug to replace an old tensioner. Not much else to say other than it works just fine.
