This 60T sprocket is just what I was looking for. It fits perfectly on my Trailmaster MB200.
added in conjunction with a torque converter. Needed my CT200U to climb hills, this did the trick
Big upgrade if you want the extra torque you get from the stock 50 tooth. Heavy duty, Easy to install, put on my CT200U-EX. Purchased with torque converter and new chain. Delivery was as stated. No issues or complaints here. I highly recommend this product from gopowersports.com
Will order another one for the other bike.
Fast service,Great response.
I bought 2 rear sprockets for our trail masters. My wife and i love them. Climbing the back trails in colorado with ease, and less stress on the engine. Take off is smoother, well worth the money spent. Placed the order on thursday, and received the sprockets on monday. Pretty cool....
I have ordered a few different times it has always Ben on time no problems really nice place to buy from
Part fit, performs as expected
I own an older model Trailmaster MB200 with a chain driven jack-shaft (NOT the newer model with torque converter) and the 196cc Honda clone. The bike was completely stock, although I bypassed the governor. I am an adult and weigh about 175 pounds.
On street, the bike is more than adequate, however, off road, I had a hard time getting up hills. I had to get off and walk the bike up several hills. I spoke with a GoPowerSports representative and asked for a recommendation. He recommended the "TAV 30-75 Torq-A-Verter" and the "60 tooth 4 Hole Mini Bike Sprocket". So, I purchased them and installed them on the Trailmaster. He was right; it was exactly what I needed! Now I have no problem going up any hills! Doesn't matter how steep or the ground’s surface (grass, dirt, rocks, etc.).
There is a slight trade off. On the street, completely stock, with the governor bypassed, I clocked a max of speed of 43 MPH. Now, on the street, with the torque converter and 60 tooth sprocket installed, with the governor bypassed, I clocked a max of speed of 36 MPH. So, there is a loss of top speed. I did not test/record the pre/post installation acceleration, but I can say, the acceleration has been drastically increased.
For me (a 175-pound adult), I am just looking for an off-road trail bike, and now this Trailmaster is perfect.
In the future, with additional modifications, I am sure I can bring the top speed back up to 43 MPH and more. But now, for me, I am very happy with the results. Thank you GoPowerSports!
