I put a 3.00 IRC GP-1 tire on the rear of my CT125, great until I rode it and felt it slowed acceleration a bit with the bigger circumference and extra weight. I installed this new 13T sprocket and it made it feel lively again, it gets up to speed way easier now. One drawback is the sprocket will make your speedo read 2mph faster than you're actually going at lower speed, at higher speedo reading at 50 actual speed 46, tested with gps.

Pair this with a 45 tooth rear sprocket (and you need a longer chain) and you get A LOT better low end torque. Nothing to brag about but if you like going on knarly trails and riding your CT125 like a dirt bike, you NEED to change the sprockets and chain! Your top end suffers bad, like 15mph slower, speedometer isn’t not accurate at all, and ABS turns off (except if you’re in 1st or 2nd gear). Highly recommend for trails!!

It's a 13 tooth sprocket, which really helps if you actually try and take your Honda "Trail" on an actual trail, as the 14 tooth sprocket is geared more for zooming about town on errands. Possibly the best / cheapest upgrade you can do to the Honda 125 - highly recommended!

I recently purchased a sprocket for my Honda CT 125. Best modification I could’ve done to the bike changed my gear ratio and actually made me go faster because it allowed me to have more power.

Great, 4-5 years in now and still in great shape. I feel far better then the oem ones that were on the bike when bought new in 2008.

Does not fit TRX-90 even though description says so. Sprocket goes on but retainer bolt holes are off 90 degrees. Believe this would only fit older Honda models.
