Folks;
I have probably over looked it some where in this forum, but what is the tooth count of the standard Vader Gen 2 grom clone rear sprocket?.
With a thrown out back I can not get down to do the counting myself.
Thanks in advance.

I counted 34 on my son's Vader BD125-8, but might have missed one or two, or overcounted. Yours is the Gen 2, so possibly geared differently, but I couldn't see Baodiao bothering.

My 2018 Vader Gen 2 is also 34 tooth , i did not have to change the tooth count at all out back as i was able to do all the "tuning" i needed with just changing front sprockets, much less expensive and also less work , and Lord knows i am one lazy s.o.b. haha!

Ok, so I did count correctly. It's not difficult to count with the chain on, but it isn't easy, either, so I was hoping I didn't miss any, lol. What is the stock front?

You can grind and make 17t work, but it;s ehhhhh. 16 fits without trouble. My old Hellcat came with 16 stock on the front.

Thanks! Is a 15t about as big as will fit on these bikes? 16t is what I run. Seems to be the best all around performance wise. Mine tops out at about ~8500rpm @ 60-62mph gps on flat ground with no headwind. 17t is probably better for cruising at high speed but at a loss of hill climbing power and acceleration.
I did need to cut about an inch from the lower part of the sprocket cover to get rid of chain rubbing with the 16t.
