I am considering buying a CBR400RR 1989 model in Smokin´ Joe colours with 43KKm (25kmiles)on the clock. Is there anything specific I need to be wary of? I´d be very grateful for as much help as possible as I am not particularly mechanically minded. Are there decent tyres still available for the recommended sizes, whats parts availability like, how setupable is the suspension etc. Thanks for all and any feedback in advance, Alex
