We tend to equate 'evolution' with 'improvement' but actually evolution just means change and adaptation and any improvement along the way is at best accidental, and often debatable. It remains to be seen whether the mammals are more successful than reptiles, and evolution often hits upon good ideas it then loses along the way (amphibians can grow back their limbs - the best we can manage is fingernails)... This is something I was thinking about as I considered my next step - an upgrade from ER6n. I developed a following list of my requirements: Engine configuration... Twin, inline4, triple? I don't care, but I want it to be smooth. I'd prefer something other than parallel twin though, just for a change. More power? yes - a bit. But actually I don't want too much, enough is enough for me. Comfortable riding position. I'm not a racer, I don't need or want a racing crouch. Fairing or at least half fairing for some wind protection. Right size for me: not too heavy, and not too tall. Reasonably priced to buy, run and insure. Good quality - by which I don't mean the latest gizmos and buzzwords. I mean it is well put together, long lasting and reliable. Decent instrument panel, as after all this is the part of the bike I'll see most often. I want clear, READABLE display showing at least somewhat useful information. (Not one of those stupid 'motogp inspired' things that look great on promo shots in the dark - too bad most riding is done in bright light!) ... guess what? There is currently NO bike on the market that fits my criteria! Sure, there are the budget all-rounders: Er6f, that new Yamaha Diversion, Gladius and GSX650F but that's not an upgrade as they are on the same level as my ER6. Actually GSX650F probably comes closest to what I want, except for being really heavy for what it is. Current 600cc class morphed into track tools that look and go great but are far too sport-focused to fit my requirements. 750 class doesn't exist any more. There is BMW800ST which I quite like but it's expensive and being another parallel twin I suspect it might be as buzzy as my ER6.Yamaha still have their TDM but it's too tall and again, parallel twin. Then I started to seriously think about the Bandit and Honda CBF, finally deciding they were a bit too much for my liking, both in terms of size/weight and in running costs. I considered VFR800... lovely bike in my opinion but expensive to buy, run and service. Those large UJMs like ZRX1200 are just too large and heavy for me to be comfortable with them. I did find a bike for me though... but, and this is where my musings about evolution come into it, I had to go back in time: CBR600F fits all of my criteria better than any of the current models. Funnily enough, when I was still on my L's a few years back I thought this was the bike I would like to get if I could afford it, as they used to cost something like 16 grand+orc when new. I guess I'm consistent if nothing else So anyway, I found a CBR600F in great nick and low miles. I'm happy with it for now, and I hope it will carry me through the next year or two... perhaps by then the wheel will turn again and something will appear on the market that will be just right for me.
