  • Quality Mod, worth while.
Size: EG428-17T-17mm Style: 17mm
Perfect fit for Boom Vader 125cc, no sprocket cover mod or new chain needed. Went right in. Speed before change 51mph, after 63mph very tucked and slightly down hill. Took less than ten minutes to put on.

  • Fits the bike perfectly
Size: 428-13T-17mm Style: 17mm
Our son had me purchase this for his 2024 Honda CRF 450 after he wore his out and loves it! Said it went on perfect, works great and looks good with the red, matching his bike. Great buy!

  • Tight fit but a must
Size: EG428-17T-17mm Style: 17mm
This really improves speed i was at 40 mph and now 50 mph. It did fit a little loos the down side is it was bigger than i thought so i had to loose the chain a lot and take the engine cover off. I still really recomened it really improves. 4 out of 5 its a must

  • Easy to install. Makes first gear relevant.
Size: EG428-17T-17mm Style: 17mm
Definitely improves the bike’s performance. The 14 tooth front sprocket that came on the bike might’ve been useful for people who wanted to do wheelies, or start up a very steep incline with a passenger on the back, but I can’t think of anything else. I had to up shift into second gear at 6 miles/hour. Consequently, I never used it, even starting out from a stop up a fairly steep incline. I would just start out in second year. This larger sprocket makes first gear more useful. Also, the bike will go up to 35 mph (speedometer reading 45 mph) without coming close to red lining the tachometer. Yes, the speedometer on the Boom Vader 125 cc motorcycle reads 10 mph fast at 35 mph according to GPS (speedometer reads 45 mph). ... show more
