Faults:

When I bought this bike brand new in 1982, it quickly developed a leaky head. That is that the head was porous and oil just seeped through. Yamaha fixed that under warranty.

I then put 32,000 miles on the bike with no issues until it needed an ignition module. That's pretty good if you ask me.

I guess you assume that I did all the maintenance on the bike, gas tires and oil, etc..

General Comments:

This was my first new motorcycle. This was also one of the best bikes I ever owned. Granted it was a 550. But, it was very quick, nimble and just a joy to ride every mile.

The XJ550 Seca was my only source of transportation for over three years. I rode it in every kind of weather you can imagine. I once rode about 300 miles in a freezing rain. That was miserable. But, the old Seca was reliable and stable.

As a tourer, I rode the Seca over a 1000 miles in one weekend from Friday night till Sunday. The seat was a shade harsh for that kind of riding but, I didn't know any different. The seating position was pretty perfect. The engine is what really shined. The 550 engine was smooth and revved up very quick. The YICS carbs were ahead of their time. Every motorcycle that I have owned since 1982 has been measured against the Seca, and many have been found wanting.

Awesome bike!

I got this as a trade, so a few things need to be fixed, but from poor maintenance.

Chains rusting and stretch, had to replace it.

Carbs needed a good cleaning.

Front forks needed new seals.

Exhaust pipes had hole made by rust, had to replace.

Cam chain is making noise (due to stretching 'cause of age), will need to replace before any major trips.

I trade a moped for this bike as a project and since has become a great everyday (around town bike).

Once I did some good cleaning, this bike ran awesome. Has always started on first attempt, till I let it sit for 3 months (then it took two attempts).

The seat is very uncomfortable after about 100 miles, gonna have it redone. They also don't make a back-rest for passenger, so I'm designing one.

All and all, a good bike in stock condition. Once I'm done with the seat, back-rest, & Cam Chain; it will be an awesome bike.

For a "do it yourself", this is very easy to work on, compared to other bikes.

I have had no real major problems with this bike. I have performed my regular services and that is really it.

General Comments:

This bike has been an overall joy to own actually.

The long distance riding tends to make your back a little sore; the seat could be padded a bit better.

Fuel mileage has ranged a little over 50mpg since I have owned it.

This bike has a great throttle response, and easily handles the quick change in gears.

The thinner tires make the cornering a bit softer than I would like, but overall it's very controllable.

This bike would make a great beginner bike for someone just starting out on a motorcycle.
