Returned to Biking a couple of years ago and started with a GS500F which kept going back to dealer under warranty. Fed up after 12 months of hassle and good reviews of GSF650SA indicated this bike would be an ideal commuter. Have to say I love the bike, with easy handling and willing engine, however I have had numerous problems. I admit I use it in all weathers and aware of usual corrosion issues if not maintained; hence clean bike very regularly and thoroughly during the winter months to try and hold off the worst. However bike has done 6,500 miles and been back to dealer twice as front brake corrosion so severe that brakes built up heat on Motorway and when I pulled in clutch to change gear, the bike nose dived and I had to drop the clutch and gun accelerate against the brakes to pull off on to the hard shoulder. Dealer said I will just have to clen & lubricate the brakes more often! Also bike has been back to dealer three times in 1,500 miles owing to the ECU / Fuel Injection needing to be re-set / adjusted to make it run correctly. Initially noticed problems when running at slower speeds in traffic, when the silky smoothness advised in some reviews was just not there. Dealer did cover cost first time, but since then I have had to cover as Suzuki GB apparently indicated not a warranty issue! As abive, I love the bike but just wish I didn't have these recurring problems. If they continue and Warrany won't cover, then bike will be history and I move brands. Shame really as this bike should be an ideal all rounder, and from other reviews it seems everyone thinks the bike is great; I must have picked up a "Friday Afternoon" one!
