14/37 sprockets 2015 Grom are PERFECT
I ordered front (14t) and rear (37t) sprockets for my Grom, both from JT and I can tell you that it made a huge difference and I absolutely love them. I have GPS confirmed top speed of 60 mph with this fairly aggressive gearing and it rips! It is way more fun than stock at a slight loss of top speed. The sprockets are very well made and got to me in one day. I won’t hesitate to buy from JT again!

High Quality for Honda Grom 2015
I ordered one of these JT sprockets, 37T for my Honda Grom back in 2018, had the part number printed on it but it was plain steal, lasted me 6000 miles before it needed replacing. Ordered a new one, same item description, received a nicer black steel version with JT stamped unlike my original. The newer one looks better quality and original from JT. If you get the solid black steel with JT stamps, send it!

Good buy
For 2024grom you’ll have to drill the hose bigger. I don’t feel much difference but that just me
