Review the motorcycles from 1973 two strokes and compare from today ; then which are the better bikes?
It would take hours to explain them all! There are a few things that are key though; 1. Better brakes now - potentially with ABS too 2. Electronic ignition (perhaps one of the biggest improvements in modern times!) 3. Better suspension 4. Lower weight due to better knowledge of materials 5. More power 6. Better reliability --Mikey B--
What do you want from the bike? Compare an MZ TS125 with a CBR125 (4 stroke) and there are so many differences that the shortest list will be similarities – chain and number of wheels. There is nothing like the same number of 2 strokes available so any direct comparison is limited.
Motorcycles have come a long way since 1973! They have disk brakes now. 5 or 6 speeds. Fuel injection. Four valves per cylinder and overhead cams. Alloy wheels. I could go on. Back in the 60s/70s friends of mine told me 2-strokes only really had an advantage on a dirt bike, because it revs up faster. They made big 2-strokes (Suzuki Titan 500, and the famous 3-cylinder 'Water buffalo', the GT750) but it was only a way to make a big engine cheaper. They pollute very badly because they don't burn all the fuel, as much as 1/3 of it just ends up in the air. And naturally they don't get very good gas mileage either!
