I like the way you're thinking adiddy. You will get way more respect (and learn more) by riding a 250 well than you will for riding a 600 badly.
I might even hang on to the VTR for a while after I've got my full - who knows?
I see you've got another thread about 250 upgrade - interested to find out if by 'Better 250' you just mean 'Faster 250'.....
