I have owned my A8 for 6 months and only covered 4000 miles but have owned it long enough now to give my views.
Economy is good at moderate speeds and acceleration; comfortably achieving 50mpg 2 up and loaded, thrash it however and you can halve this. Tank range up to 300 miles, going steady. Comfy ride for both rider and pillion. Good weather protection but found feet get cold unless tucked right in. Contrary to reports, servicing is reasonable being quoted £180 for a major service (8000). The interim being checks, I intend doing myself. Enough power to put a little grin on my face. Easy to ride and throw around considering its size and weight. I’m 5’7” and 11 stone!
Mirrors adequate, but do make excellent wind deflectors. No gear indicator, power sockets are an extra. Not experienced weave but have only done 120! However, becomes very light if the wind is strong enough (at low speeds too) and in the wrong direction – I’ve put this down to the wing like shape of the fairing, which appeared to give the bike some lift. Economy around town is very poor so use my car to commute, as it’s cheaper and the bike’s size prohibits efficient filtering. Exhausts a little too quiet.
Love it, you can get loads of extras (at a price) but know it’s going to last!
