I keep a 'relatively' cheap 2010 Suzuki Bandit 1250 in my armoury. Just put new tyres, new battery, new chain and sprockets, new clutch fluid.
Cheap as chips to run and insure.
Last year I stripped it down myself and fitted new head bearings, new handlebars, heated grips, new mirrors, CREE LED lights, new Wilbers fork springs and seals plus Wilbers rear shock, engine bars, new rectifier, new spark plugs, air filter, engine coolant, oil and filter, brake pads front and rear with HELL braided hoses, fork brace, akrapovic carbon exhaust, pillion streetfighter cover, stomp grips, garmin sat nav, givi racks.....
Ahem.... did I say cheap as chips?
But great fun, totally enjoyed messing with it. ... and its quick for a naked bike.
