    Very nice upgrade. Does everything advertised. I only am giving this a three star because I bought two for my father and I’s Monkeys. Unfortunately one did not fit. The 2nd one I purchased fit perfectly.

    Very easy to install. I also purchased a new gold chain from MNNTHBX. I installed them at the same time. Noticeable difference in acceleration.

    I bought two of these sprockets last week and when I received them they were the incorrect sprockets. The correct part number is JTF249-14 and I received JTF273-14 sprockets. I emailed Mnnthbx about the sprockets on Monday and I received an email back from Zack who said he would ship out the right sprockets as soon as possible. I received the new ones the next day. I am very impressed by the team at Mnnthbx and their customer service! I’ll continue buying my monkey parts here.

    I bought a JT 141 countershaft sprocket for my 2023 Honda Grom. The product arrived quickly and was a perfect fit. This is the best and least expensive upgrade for a Grom. I would recommend it for all Groms that are mainly ridden on the street. and MNNTHBX is a great place to buy from.
