I noticed on several post that there is an 11 tooth front sprocket for the Redcat MPX70 and MPX90. Does anyone know if the MPX70/90 uses a #420 or #428 chain. I am wondering if this 11 Tooth sprocket might fit the Mini 90?s (Sunl 90, Roketa 90, BMX 90, Raceway Mini 90).

 

I have a mpx-90 and I'm not sure what type of chain it uses I ordered the 11 tooth sproket from redcat their parts website is atvpartsusa.com if you call raceway they can probably tell you what you need. I will tell you this I went from 14 tooth to 11 tooth and the 11 made it a completly different atv climbs hills great now takes off good well worth the money
