Went from a 13T front sprocket to this 17T on my daughters 110cc Coolster…. It went from high rpms at 15 mph to 22 mph and still has plenty of take off power

  • Fits 2019 Honda Grom
Size: 420 14t 17mm Number of Items: 1
I used this for my 2019 Honda Grom, fits good. I got the 14 tooth, if your looking for stock gearing it's a 15 tooth. Going down to 14 gives you more torque but less speed. Stock, my Grom could go about 68, with the 14 tooth I was topping out at about 59. I also tried a 16 tooth, topped out at about 72. ... show more

  • Does not fit apollo Dbx-19. Makes my chain rub against the in side of my sprocket cover
Size: 420 17t 17mm Number of Items: 1
Exactly what the title says. I purchased the 420 17t 17mm so I can get more top speed on my 125cc DB-x19 apollo only to find out that when I put my sprocket cover back on the chain started to rub the inside of the sprocket cover when the rear tire turned and it doesn’t help that my chain is a 428 and it’s already tight as it is. If I somehow find a solution to this then I will change my rating but until the it’s a one star for me. ... show more

  • A little extra pull
Size: 420 12t 17mm Number of Items: 1
I used this on a 125cc Coleman mini quad to help it on hill climbs. The smaller front sprocket helped a bit, which is all I was looking for. Install was simple.

  • Ordered a 420 12 Tooth received a 13 tooth
Size: 420 13t 17mm Number of Items: 1
I received the wrong size, but luckily it still worked much better than expected. So I think it actually works in my favor, less loss of top speed.
Reviewed in the United States on November 4, 2023 by Does anyone know the replacement size for the watch band or even a lanyard? My son is 3.5 and I'm sure it will be too big and I'd love to find a way that he can't take it off. Suggestions?
