Fit perfect on his SSR 125. Changed the whole operation of the bike. Went from a 14t to 17t. Now we can ride in 1st. B4 this upgrade 1st gear was almost unusable. Highly recommend this if your running a 14t or 15t sprocket.. Worth the money. Its a clean, well manufactured and quality upgrade. ### ⭐⭐⭐⭐⭐ Great Upgrade for More Top Speed *by K***G on February 28, 2025* I bought the 16T front sprocket for my 125cc SSR ATV to get more top speed, since my OEM was only 13T. The difference is noticeable. first gear is much more usable now, and I definitely get a higher top speed. Installation was easy, and the quality seems solid. Looking back, I wonder if a 17T might have been even better option ### ⭐⭐⭐⭐⭐ Worked perfectly *by R***S on June 24, 2022* I bought a Honda Little Cub with a Daelim 110cc engine. The Little Cub cake with 14 inch rear wheels, the Daelim 110 engine was made for 16 inch, so the final drive was wrong, too short. This sprocket fit right in on the Daelim engine, and made the gears taller. The top speed of the bike went to am acceptable 85 km/h after the switch.
