I've had mine for just over 3 years & absolutely love it but jings crivvens they are NOT cheap things to service.
They need servicing every 3,500 miles & each one of mine has come in between £180 - £250.
At 14,500 miles the belt & pulley are recommended to be replaced. The Suzuki belt is just under £300 & a main dealer 14.500 mile service including belt & pulleys is getting on for £550.
I had mine serviced at a non Suzuki garage who inspected the belt & said it should be fine until at least the next service but as I say, it's potentially eye-wateringly expensive.
On the plus side if the belt should snap it won't damage the engine & the worst case scenario is a phone call to the breakdown company & a long wait for them to arrive.
