  • High Quality!!!
Color: Blue
I was unsure if this pitter was going be worth the $ or not being there was zero reviews a you really couldn’t find much about this particular one. What made me decide to get it was the inverted forks an the heavy duty looking frame. But right outta the box this is a legit real deal pit bike. It has super nice & high quality pegs, brake lever, bars, switches, etc etc. It comes with a Japan Kehin carburetor but I swapped it out with a Nibbi carburetor I had laying around here at the house but the Kehin needs lil tuning other than that it’s a great quality carb. I’ve owned pitster pro, ssr, Tao Tao, and this one easily is a good or better quality than those I just mentioned. If you’re thinking about purchasing this bike but are worried about the quality believe me is def worth the $ an I highly recommend this lil bike for any adult or advanced kid. I weigh 200lb an was able to set the sag with no issues an suspension performs well straight outta the box. Would be even better if you revalved. Overall I’m tickled pink with this bike a would def buy another one without thinking!!! 5 outta 5 ... show more
