How much???

Then you're thoroughly mistaken! Remember, the Mk1 Tmax cost £6,000 when it was launched, way back in 2000, and has sold like hot cakes (sur le continent) ever since.
[quote=] £10k? You could get numerous (proper) bikes which will do everything better in every way for that kind of outlay. Seems BMW are relying on their badge marque.[/quote]
You imply that a maxiscooter is not a 'proper' bike. I beg to differ. As far as I'm concerned, the Tmax, Burger King and both BMWs are all automatic motorcycles masquerading as scooters. But they're all more relaxing to ride than almost any bike and much more convenient for carrying shopping and sundry other bits and bobs. Remember, the BMWs have more power than the original Honda CB750 and as much as the fire-breathing Kawasaki 500 triple two stroke; and they handle and brake far better than either, with a lot more comfort and weather protection to boot!
Having said that, I do think the BMWs are overpriced. BMW should have taken the Burger King Executive (£8,200 with all the bells and whistles) as their starting price point rather than the Tmax530.
