420 Taotao, Kayo, SSR Chinese Front Counter Sprocket (Upgrade)

3 yr olds 110 was way to fast at 30mph with the stock sprockets(14 front/37 rear). I went to 12 on the front and 46 on the rear. It's now 20 mph with full throttle. I can now govern the throttle for 10 to 15 mph and still have plenty of torque for hills. Get the modified retainer for the front sprocket. This setup required a chain that was 4 links longer than stock. Also had to snap off the flimsy skid plate under the rear sprocket. The plastic chain guard still fit.

Ok for starters I put this on my daughters TAO TAO 110b ATV we were looking for more torque and lower TopSpeed she's only 5 and it didn't have the torque to go up the driveway with her on it from a dead stop. I installed this with a 49tooth rear sprocket giving me just over a 4/1 ratio. Now even with the limiter turned way down it still goes over any thing she comes across on the trails we ride. And with the new sprockets I was able to give her a little more throttle to play with geting her in to the higher rpm range and still keep her top speed nice and slow. The "but" part is even if you grind down the retainer you will still hit the bolts on the chain so you will need to change out those too or add some washers or other spacers on the bolt to keep the chain from hitting. So in short I wound up swapping more parts than I planed but it worked out great and the quality of the sprockets is much better than oem. *** We do offer a hardware kit for the clearance issue***

I bought this to re-gear my kids 125 TaoTao ATV. I originally ordered the wrong product for this and the guys at Whygostock contacted me to let me know how to find what I needed. The front sprocket is stamped with 420 or 428. Once I found that out they shipped the correct parts in about 3 days. Previously the ATV wouldn't go over even the smallest bump or incline from idle with my kids on it. Now it will go up the ramp and into my tailgate with me on it. This worked awesome! I I went down 1 tooth in the front and up 3 teeth in the back. I did have to replace the chain. All said and done it took about 1 hour. This really made the ATV usable.

My son's 4 Wheeler is a 2015 125D TaoTao. The front sprocket was a 14T and the rear was a 40T, this was the stock sprockets. I replace them with a 12T and a 42T. It made a huge difference. He was able to go up hills with ease where he wasn't able to in the past. He is 9 and weighs about 80 pounds. I did have to file down the ends of the retainer clip for the front sprocket. It was simple to do. I also did some other upgrades filters, spark plug, etc. He didn't lose too much speed but has a lot more low and medium power. Much better for trail riding. The original chain worked with this setup.

Fist the product(s) I ordered are great. I ended up ordering a 12T front sprocket and a 44T rear sprocket for my kids TAO TAO 125D. You have to shave down the front sprocket retainer ring just like others have and replace the stock bolts with an allen head style or the chain will hit on them. The 44T rear sprocket being larger, I had to cut off the chain guard on the frame (which is crap to begin with) for it to fit and I will be cutting the brake caliper chain guard off as well and making a new one myself. I haven't tested the quad yet since I'm still working on them, but with everyones review on the 42T rear using a 12T front saying the difference is amazing, I can only imagine with the 44T. I will post a follow-up after Im done... FANTASTIC customer service and FAST shipping - VERY HAPPY Customer and I will for sure re-order with this company! Thanks :)

Exactly what I needed, full specs made selection easy. Prompt delivery and fitted straight on

I called to verify information before I ordered. I live in Michigan and I ordered the sprockets on a Wednesday and they arrived Friday. I have 3 TaoTao 135D for my grandchildren to ride. I purchased a 12T for the front and a 42T for the rear. I did have to file the retainer plate a little.(as instructed) I also had to bend the chain guard under the rear sprocket a little to clear the chain. I also installed new heavy duty chain because I needed a longer chain with the change in the rear sprocket. I weigh about 210 and I noticed a definite improvement in getting moving from a dead stop even in rough terrain. I needed more power for trail riding and this solved the problem. Very happy with the product and service from whygostock.

I purchased the 12T sprocket for the TaoTao 125D and it fit perfectly. As the description says you do have to file down the sprocket retainer plate, which took a whopping 3 minutes with a file. I noticed a difference in the acceleration from a stop, which was the goal. Happy with the product and very happy with the customer service I received from the whygostock staff.

Fast shipping excellent service and product was just as described.
