There was a time that the motorcycle press called all inline 4 cylinder bikes Universal Japanese Motorcycles. I think it painted the market rather badly. I've never had a Suzuki. This is a top flight UJM.
I've never ridden a 70 before. I never had enough money to buy a used one when I had my paper route, then pretty much I outgrew this sized bike. I see these on Craigslist occasionally and a nice one can cost $1500-2000.
