So right Mike. The cost factor is the thing.
I just sold a very good CX500 Eurosport ('lectric leg') to buy a T140 Bonnie (needs a real leg!). MADNESS you'd reckon, me with a stuffed back, a new heart valve, emphysema and half of one lung left! ...
What? Why would I do that? Well the Bonnie will be almost as quick as the CX (yes), but it weighs much less, AND, it's got 'soul', AND it makes a noise that's a real jack-up.
I've got it semi-sorted, so it's a first kick starter. Maybe... just maybe, it could be an 'everyday user' Brit vertical twin. I'm hoping.
I just can't see my dear SR with it's oil leaks (sep G/B) and ***-weak dynamo being the whole deal. An electric starter (along with attendant upgrades) would get it a whole lot closer, but at a big price, and you're still left with, well a machine that, whilst I love it, just wouldn't cut it for everyday use.
