Bought mine new august 07, 14000 miles on it now, used daily on a 33 mile round commute.
Rust appearing in most places, centre stand has to be pushed back up manually as no longer springs back up, I only have to look at the paintwork for another scratch to appear, neutral light doesn't always come on, the rear brake pedal jammed up 3 times last winter each time had to be freed with wd40 ( this is to be expected according to a Suzuki mechanic! ) , and today while washing the bike the paint on the rear wheel literally peeled off in front of my eyes!
The gearbox is rubbish as well.
Also be aware if you plan on doing high mileage, the servicing costs are astronomical and need doing every 4000 miles. It is cheaper to service my car (Citroen C4) at a main dealer than it is to service the Bandit at a Suzuki dealer!
Tyres last around 5-6000 miles, and the original chain lasted just under 12000 miles by the skin of it's teeth! I was advised at the 8000 mile service it was on it's way out.
On the plus side, reliability has been faultless, the engine will probably still be running when everything else has fallen apart!
To sum up, the Bandit is a fine bike for warm weather riders, but if you are looking for an all year round commuter, stay well clear!
