I too have a 70 sx750. Rode is 900km´s this week. Two new tires and oil change this week too. Live in Nova Scotia, Canada. Weather is good now for riding. Mine has Yamaha brand crash bars, hard bags on the back and front fairing. All Yamaha, and original Yamaha paint too. This is a very nice bike and proud to own it. It has just turned over to 39,000 km´s or about 25,000 miles.
