+8Rich is right. The discs are inboard but unlike the Citroen you can get to them! Good positive feel too, but then it's so light. Good to relearn cadence braking.
I definitely drive it more slowly than the M3W as the soft ride takes some getting used to and it leans/rolls. The later models have slightly stiffer suspension. Have covered about 500miles this summer and have a much better feel for it now. One unexpected bonus it's really practical. Tilt the seat back forward and there's your storage plus the 'glove box goes the length of the bonnet (or hood LOL). I always hankered after the polished ali bodied Brooklands M3W as I loved the look and Autoglym metal polish and a chordless polisher do the job quite easily.
Sounds fantastic. You can enjoy safe three-wheel driving now.
