The best hmmmmmm. So many good bikes. I have to pick from ones i have ridden and that includes just about everything mentioned so far. I can't comment on JMCs and Changas.
Cosmetically the large gusset Turbo gives me wood everytime and when it was released i would say it was the best stock package available bar none. Having now ridden one they also ride great although i found the DB Pro bars a bit small.
Rippers also give me wood but they are expensive, poorly designed and they break. The Quad i had i had no complaints about but it was too long for me.
The Pro Class i never rode but it was/is an awesome package. The Hutch Pro Racer i had was ordinary. The Redline 500A i had was a great bike for the cash.
The Ta i had was hammered both on track and at Rom out of the tunnel bowl and despite egging two araya aeros landing on flat concrete i couldn't break it. great frame.
The GT Pro was Ok.....
Still my favourite and first real BMX was the 1983 Torker 280.... 23Lbs and £199. Short, light, strong and flickable. I put that bike through everything and it eat it all. A hugely copied twin toptube design. Great to race and great to freestyle. The forefather of the Haro and many others.
Torker it is then
