FVRITO Mini Bike Chain Tensioner for Predator 212 Coleman CT200U-EX CT200U | 1-3/4'' Roller, for BT200X Baja Massimo MB200 MB165 TrailMaster Minibike Parts, Metal Construction, Improving Transmission

It does the job and you’re even able to connect a spring to the side of it and have that spring holding it tighter tension. The tighter the tension the higher chance you got of your chain snapping be sure to lube it up and know it’s gonna handle 35 chains and 40 chains no problem been running it for a year on my mini bike!

Easy to install. The quality is good for the price. It’s durable

Keep on rollin

Fit perfect. Operating perfectly.

Grabbed this FVRITO chain tensioner with the 1‑3/4″ roller for my mini bike—and it’s been awesome so far. Super simple to bolt on, and the big roller keeps my chain tight and clean, no more weird slack or skipping gears. It’s solid metal too, feels way sturdier than the crappy plastic tensioners you see around. After riding a few weekends, no signs of wear or loosening. Heads-up – you gotta space it right so the roller hits your chain just right, but once you do it’s smooth sailing. Definitely a solid upgrade that was totally worth the few bucks.

I know this tensioner is for a jackshaft, but I bought it for use on a FRP GMB100 with a Predator 224 swap. The chain tensioner on the bike didn't have enough adjustability and you can't reposition the engine very much. It took some figuring out and a zip tie to get it on, but the spring isn't strong enough and kept throwing the chain and bent the tensioner on the second test run. Ended up just snugging down the bolt to hold it in place in the upper position to provide tension. It would be much better if they provided a stronger spring.(Update) the swing arm on this thing can't take any amount of force, it just bends, DO NOT RECOMMEND

Quality seems good we'll see about durability
