I am looking for an older easy to ride motorcycle?
First things first, you want to stick with an inline 4 cylinder. as a new rider, even though a bit heavier than twins they are better balanced and handle better. Also, as a 200 pound guy you want a big enough bike to be comfortable on.
2nd, stay away from triumphs. They are GREAT classic bikes and are very neat, but should not be a first bike by any means.
What you want is one of the following.
honda 550 four/Honda 650 Nighthawk.
Honda's are very reliable old cheap bikes. They are a bit top heavy and do not handle quite as well as some of the other older 4 cylinders but they are very mechanically sound and easy to maintain. least powerful/speed.
Kawasaki KZ 650. Propbably the best of the older 4 cylinders. Very relaible, handles great, easy to find parts for, and a fairly fast bike for its time. My personal choice. (I own 9 KZ's of various sizes, including 2 650's.)
Suzuki GS 550/650. A basic mix of the 650 KZ and Hondas. good reliability, good handling, and good power/speed
any of these bikes can be found foras little as 2-300 ready to ride. They may not be the prettiest, but since they are from the late 70's early 80's they got some years on them. Also, before you shrug off a bike that old, it is possible to find them with 15000 or less miles which is often less miles than you would find on a late 80's early 90's bike and simple maintance is 1/3-1/4 the cost as the newer ones as the filters and plugs are easier to get too.
When you factor in insurance costs, repair work, and other things a UJM(Universal Japanese Motorcycle) is by far the better choice. Also, if you can work on a lawn mower you can do most of the maintance work needed on the older bikes.
Ride safe, ride smart, and ride fun and if you havent ridden any yet, take a safety cource as they provide the bike in most cases and you can get a discount on insurance.
