It is what the RTA have on their books, but... It's not the base model.

According to the engineer I spoke to up here (not about Minis, but conversions in general), it's whatever the heaviest (Tare mass) sedan/saloon available in the year of your vehicle's manufacture.

I was looking at a Ute (Morris Minor), and it was off the weight of the 4 door saloon for that year/model (which is roughly 50kg heavier than the ute, and mine doesn't even have the steel wellside tray anymore

). Which, in the case of the Minor, means that the Series MM - the earliest ones, the ones you'd feel most guilty modding - can have a bigger engine than the others, because the original side valve engine was heavier than the A series which replaced it.
Anyone else find it interesting that the Workshop Manual D1ck0's looking at lists the Moke as being heavier than the Mini..? Not the first time I've seen that, but it's not the common belief.
