I got my first CB350G at 15 in 1973. Back then the speed limit was 70 and I used to go everywhere. We'd tell our parents we were going camping and head to Panama City. I had it 8 months and put 18,000 miles on it before I totalled it on Miracle Strip passing cars on the right side
.
Anyway, I weighed 165 back then and would ride 2-up at 70 mph for hours on end. Mind you, it's 7,000 rpm with stock gearing (tach and speedo are exactly the same in 5th gear), but they are super tough. I have it's replacement today and I'm 240 and still love riding it on nice afternoons.
One last thing - did you realize that is a 1 year only bike? It's paint, it's disc brake, it's instrument lighting, and gauges are all a 1-year only model. The best and last year of the CB350 twins. Don't chop it up. They are a piece of history.
Regards,
Gordon
