You need a Burgman 400.
I've been thinking about that or the Piaggio BV350. Slim is very important for getting between cars on Calif freeways. The B400 is nice but a little bloated in the width dept. The Grandvista / Dink really hits the sweet spot offering slim with great wind protection (with a taller wind shield), Storage under seat & givi top case.
Grandvista / Dink improvements:
1. larger wheels 15" or so for better ground clearance and tire choices and handling.
2. 350cc motor.
3. Softer suspension with more travel.
4. slightly larger gas tank - 3 gallons.
5. Regular mirrors - side mirrors are nice but break too easily and my local dealer charges $180 each OTD with shipping which is a bit steep.
6. Slip-on exhaust header so you don't need to drop the entire exhaust to change the rear tire - or fix a flat.
Have you ever owned the B400? What about vibration at the handlebars?
