Not my first bike, but on Mavs theme about model development my first of 3 slightly different models of my first V twin was not the best but it lasted the longest.
The very first model of that superb torque laden V twin had an indellible effect on my biking life for evermore. The handling was interesting and the engine was predictable, insomuch as it would need stripping every 30,000 miles, but other than that, ran for well in excess of 120,000 miles on the clock, but in reality quite a bit more. (broken speedo drives).
The second model of this superb beast had benefitted from factory mods/redesigns even though they denied there was any problem. This engine performed superbly, with no need to strip it periodically and ran absolutely faultlessly for over 60,000 miles before some sad thieving scum nicked it.
The third model was memorable only for being suposedly more refined and developed but was actually a retrograde step, and not really that memorable. Heavier and despite supposed progress the handling still left a little to be desired when on the ragged edge.
The bike that converted me to V twin power that i refer to was the good old Hondahaha CX 500.
The first model ate cam chains every 30,000 miles, plus the odd alternator.
The second model the wonderous CX500B just took all the abuse i could give it and was faultless.
The third model, the not so awesome CX500 Eurosport was considered by connoisseurs in the courier world to be overweight and lack the svelte looks of the original model.
So from my experience the second model was the best as the teething problems of the first had been ironed out but the performance and handling were just as exhilarating.
And for any of you doubters out there about CX500's i still have a copy of an article written by Roland Brown in Bike who refers to the fully laden despatch CX500 duffing up a 350LC through south London. How we laughed and how it wobbled.
