I upgraded this bike with a makuni carb,better sparkplug, air filter and a 17t front sprocket.bike is awesome ran it hard for for over a year now and it's still riding.

The only issue I had was changing the oil twice. I changed it once after running it with new oil for a couple of trips, and then again after 2 to 3 hours. I gave it 4 stars because the paperwork took a while to arrive and delayed our riding trip by 2 to 3 weeks. But it was still worth it. I recommend getting the AF carb kit. It makes a big difference.

This bike has a great look and feel, but you need to change the carburetor to make it run better.

This bike is awesome. I'm 6'2" and 215 lbs with a 34" inseam, and it has enough power to carry me around easily. It's fun to ride a small bike with my kids on their 125cc ATVs. We enjoy riding together in our yard and on bigger trails. The suspension is better than I expected. I can jump it off a 2-foot berm in the backyard and it handles well even with my weight. The only problem I had was a loose catalytic converter under the heat shield of the header pipe. It made a lot of noise, but I fixed it by bending the pipe a bit with a hammer and punch. Now it's quiet. You need to be good at fixing bikes to have fun with these things. They need regular maintenance. Check the valve clearances after assembly. Mine were too tight. I set them to .007 for exhaust and .005 for intake. It runs great like that. Change the oil often. Break it in gently. It will last if you treat it well.

The bike came in good shape and well-protected. It was bigger than I thought, but it fits me well. I'm 5'9" and 150lbs. The bike is awesome. The stock exhaust sounds great, and it also arrived early. I had a great experience once again.

It was hard to assemble it by myself, I needed another person to help me. The bike has been sturdy so far, nothing has broken. It stutters at high speed, so I bought a new carb to adjust the bike. Overall, it's been good so far.

I decided to buy this instead of looking on facebook/craigslist, where people ask for 1k-2k for old dirt bikes that barely work. This thing is amazing. It was the best thing I bought from here. It was hard to put it together by myself, but I managed with a car jack. It's fast and agile, and not too loud, which I was worried about because I live in a neighborhood. It's perfect!
