Powerful 2-stroke bikes proves to be the popular choices in 70s and all the way until now as of 2014. There are plentiful of legendary bikes that are still available in secondhand market like the aggressive Yamaha TZM-150, the iconic Honda NSR150 SP with the single-sided ProArm rear suspension, the naked Suzuki TXR 150 Gamma and the last 150cc 2-stroke to arrive, the 2008 Kawasaki Ninja KRR ZX150. The sound these 2-stroke bikes are among the best sound you can hear on the road and track. In 2014, many 2-stroke bikes are going to be discontinued, so here, I copy the actual text and images so that it will always remain online for those who are looking to refer to it again. The official text and images are as below:
