The air cooled 1203's as well as the new 1125 are nothing close to a starter bike...bad idea.
I understand your concern, if it were most peoples choice I'd be riding on a Buell Blast for 12,000+ miles until I could even step up to a Ninja 500. I know everyone is just trying to look out for the well being and safety of others but I think people tend to exaggerate the OHV liter V-Twins power....alot.
Lately I've been getting alot of ride time on our three dirt bikes here. A 125 2 stroke, a 250 2 stroke, and my 200 4 stroke...when it works. Everyone told me I can't handle the 2 strokes, that they're potential death machines even idling and that if I get on it it will be 100% guaranteed pure death....
Then as I was frustrated at my broken 4 stroke I got on my fathers racing geared Suzuki 125 2 stroke...and after 2 hours of slow familiarization with the bikes handling, clutch, and gears, I was ready for a cruise... All I could think about the entire time was "Man, forum go'ers kinda uhm...exaggerate power...alot"
I would never
buy a liter I-4, but if I want a Buell and they only make big v-twin's I'm not going to settle for a moped and be unsatisfied for years to come.
