24k is bordering on despatch territory. So, get an East European to taxi you around on the back of his 125 scooter/CG125/KTM950 (with czech plates with too many numbers and not enough letters

.
But before the 1990 redundancy torrent killed the industry (man in factory buys GIXER on HP over 5 years, gets made redundant, becomes despatch rider, oversupply of riders, riders who are not budgeting for tyres and chains let alone depreciation. One year later, faced with a wrecked bike, and no money in the bank for a new one, chucked it in a hedge and claimed it had been stolen. Insurance went through the roof, and business, pissed off with an unprofessional industry found new ways to make email/the net etc work for them.)...er, where was I ?
Yeah, before the industry died...CB500, Deauville (or NTV as it was in those days - Revere anyone? as in Paul Revere
http://www.paulreverehouse.org/ride/
the most famous despatch rider of all time, only Honda failed to realise that an American National Hero could be unheard of in England), R850R (last bike I saw offered as a company bike), or the K 75/100/1100.
Personally, I would go for the CB500 'cause I have never had one (and 'cause I have a scottoiler in the garage I bought for my Yam DT125 but never fitted 'cause you have to drill a hole in the carb), or a K1100RS. Or a K75RT. Or an R850R. But not a K1200S. The wrong thing altogether IMHO (too sporty, too heavy, too expensive to run etc etc)
Alternatively cast yourself back
