YCF Pitbike

Actaully they are pretty good, i have 2 bigy 190 models, and have them setup as a super mini, so takes them out of the pitbike class, will be posting some pics this week. They also make the Pirahna brand which are their racer models. A 140 and 190.

I bought my wife a 110 a couple years ago and they are pretty decent for the price, would buy another

I have a 140. It's a real race bike. Seems to be holding up just fine other than the brake friction material that is a bit grabby and squawks. @190# the suspension even holds up decent. It has about twice the HP of a stock 110.

We have a F125SE used purely as a pit bike. It's been solid for 30 hours. Front springs are a little light for my 190 lbs but it's got plenty of power and the build quality is just fine. 

I have a couple of the BIGY 150s and love them. Replaced the fork springs with some stiffer springs and added air valves. For pit bike racing they are great. The BIGY models have the 17" front and 14" rear wheels  and its sits about the same high as my 78 YZ125 did so I'm not cramped while riding. Will buy a Factory Daytona model next and maybe a couple of the Sunday flat track models. We have a great time riding the 150s

I will get a couple of these next. 

We have sold quite a few of them and they are solid for the money.  Have seen them tortured and hold up!

Good bikes. Had a 2018 Pilot 150. Much better than any other Chinese bikes. Good power, good brakes and decent suspension for my weight. I loved it. Worth the little extra you pay for them over the cheap ones.

Millers cycle sales them here in Inman Kansas. Josh that works there hangs with the super mini class and has even had parents fighting mad for smoking juniors A kit 105 on a pit bike lol. I know for a couple of guys, They moved and rewelded the peg location some but other than that. I've seen these things beat on just as bad as any other brand and keep right on ticking, Getting at least 4 for the grandkids. 2 moto, 2 flat trackers.

Ive been racing a piranha 125 the past 2 years, only problems i have had is the trans. Maybe the 140 or 190 would have been better idk. But ive had to tear the engine down 3 times now. Also had a stator go out during a race one time.
