"Maybe Im too stoopid to understand"
I thought the same for me, so I did some digging. From what I've read, there's subtle ergonomic and accessory changes, with the Bullet being the more basic of the two. Aesthetically, I think the Classic has a more "British retro" look with the Bullet being more "Indian retro," and that may be the biggest difference.
- Classic has a larger rear brake (270mm vs 153mm) according to one site, but another says both have 153mm.
- Classic has a higher ground clearance (170mm vs 160mm)
- Bullet has a "stand alarm" while the Classic has some indicators the Bullet doesn't: low oil, low battery, and a clock.
- Bullet has a pillion grabrail and seat as standard, and the Bullet's seat is reportedly comfier than the Classic's
- Bullet has taller handlebars
- Wheelbase is the same, but the Bullet is a little shorter in length (different fenders)
- Bullet doesn't have things like the tripper, a passing flick switch, etc.
- The starting Bullet price is about 10% cheaper than the Classic in India
