It may be part of a recession trend where people are temporarily giving up motorcycling or 'downsizing' to smaller, cheaper bikes - are there also a lot of other litre bikes for sale?
Remember that interest in buying motorcycles grew by some 500% in the nineties and where there was boom, there's now bust
Prices.....well, a seller can state any price they're looking for their bike, but whether they'll get it...
