*Steel 428 Conversion Kit - Superlite RS7 Series 428 Chain & Steel Sprocket Set - HONDA MSX 125 Grom '14-21

Stock Gear Ratio - 15 Front | 34 Rear 

Our new Superlite 428 steel conversion kit for the Honda Grom is the strongest drive kit on the market today. If you're tired of getting poor mileage out of the stock 420 pitch chains, this new 428 kit is the way to go. All kits include high quality Superlite Sprockets with multiple gear ratio options and high strength Japanese manufactured chain cut to length.

For increased acceleration and torque, select a one tooth smaller front sprocket or a larger rear sprocket. For better mid-range and top speed, just do the opposite. Keep in mind that one tooth on the front sprocket is equal to 2.5 teeth on the rear sprocket. The stock gear ratio is noted below and once a gear ratio is selected, we will cut the chain to the correct length.

Each sprocket kit includes -

(1) Superlite XD Series chromoly steel drilled and lightened front sprocket

(1) Superlite RS7 Design black plated C45 steel rear sprocket

(1) D.I.D. heavy duty 428 non O-ring or heavy duty X-ring sealed chain cut to length      

(1) Matching clip style master link 

*Sealed chains lasts 3-4 times longer than the non-O'ring option.
