Come on here, this is DHM. You really think they're gonna sell any junk that's not up to the DHM standard, ha, ha? The Speed Shop did a great job of updating the design on a common part to fail in these engines when we start to push the limits or even stack on those miles. If you're considering this part for your build, do it. There really isn't a better tensioner out there that you can buy, there just isn't! #grombeardoapproved
The Speed Shop has released the latest solution to the failure prone tensioner system in the 2014-2021 Honda Grom and Monkey engines.
They’ve utilized a true roller bearing system which is far superior to the journal bearing designs. This prevents failures at higher RPMs and is a bulletproof system when paired with the Decha Manual Tensioner system.
