In the early 70s to around 1985 was the RED HOT Era of the 2 Stroke Pocket Rockets. The Yamaha RD Series really had this market really hopping with these fast accelerating and wheelie and brakie popping machines. I have had 3 Yamaha RD 350s and 1 Yamaha RZ 350 and even a 1978 model RD 400. And they were really great bikes for that era of Time in technology. It was an absolute RUSH to launch off the line with the front wheel beginning to rise to the sky! The heart was going 90 miles to the minute and the Bike seemed to be begging for more...A really fun time in History for the Small Bore high performance Motorcycle!
Fast Forward to 2018 and once again the New Wave, New Technology is here with the New Ninja 400. And this will probably be the New King of the Small Bore Pocket Rockets. The Demand seems to be really Intense to see this New Bike to come to market. The Styling, The Speed, and the Performance to say the least. From the U Tube Videos we see this Bike light up the tire and pull a huge wheelie and then accelerate to Speeds up to 195 to 201 K. And perhaps even more when modified. The Insurance is lower and even the Gas Mileage is even higher. And it will bring back a lot of 1970s memories of me blasting all over town on my Pocket Rocket that no regular car could even touch. Just wanted to play the Way Back, Blast from the Past Memory Machine.
