A Brief History & My Thoughts

While looking through Craig's List one day I came across this bike. It was love at first sight! I had no previous experience or even any knowledge that Yamaha had built a Turbo bike back in the 80’s. But when I saw the photos and read the detailed description, I was hooked.

In a nutshell, Eugene, the guy selling the bike, had purchased the bike many years prior from a collector in Nevada. Eugene had once entertained ideas of showing the bike and then selling it on for a tidy profit, but it just didn’t come together for him. He was thinning his bike collection and this bike had to go.

Now the bike wasn’t in mint condition, but as you can see from the first photo, it was in very nice cosmetic condition. It had just a bit over 6000 miles on the clock when Eugene purchased the bike, and now it had 2 more from the time he had owned it.

I went to look at the bike in person and was told that it wouldn’t start without quite a bit of work and that was the main reason for the asking price. Apparently Eugene had paid almost $1000 to have the carbs rebuilt, but the bike still had a problem. It spun over easy and looked great, so we completed the sale.

This Motorbike Is A Joy To Ride

Where most vintage motorbikes are rough and ready, this bike is so smooth and refined. It has air assisted suspension front & rear and a super comfortable seating position. The comfort and smoothness is really quite startling after riding one of the other vintage bikes.
