Hello all, Il write a little bit about myself to see what you'd say would be best for my current situation. I'm 26 - 8 years driving experience, 6 months motorbike experience. (UK here) I commute to London ( outskirts ) which is a 60 mile round trip. I use a Yamaha YBR 125 at the moment on A Roads I'm not after speed but I get upset on my 125 when a little bit of wind keeps me at 55mph at MAX rev. I need to be able to hit 70-80 ( not going to speed ) but at a comfortable going. MPG is also a big thing too for me. SOOOO... il support this thread with lots of research , but what should I aim for between a 250 and 600cc? will a 250 do it for me without feeling like i could instal some peddals on it to get an extra 1mph in the wind? 600cc is available but I will need to restrict it if I do only the A2. Which is why i might consider the DAS. If i restrict a 600cc to 35bhp, what happens to top speed and torque? Will it feel like im riding a heavy 250? Im so stuck with path routes and engine sizes its just a lot to choose without being able to change my mind. And as a beginner, theres limited ways to test ride bikes and so on
