I've had a lot of Suzuki's, from the GS1000 i had in the early 80's, through to the V Strom i had only a few years ago. Can't remember any real reliability issues with any of them, probably been as good reliability wise as any bikes i've had from the other 3 main Japanese manufacturers. The only quality issue i've had with Suzuki's has been the paint, its often thin in places, especially on the wheels, forks and engine, where the ally will often oxidise underneath .
Honda always used to be top of the tree quality wise, and were always the most expensive, but they're all much of a muchness now. They're all competing on price and corners get cut in quality.
Most unreliable bike i've had was a Triumph Tiger 955i that i bought brand new back in 2005, i had numerous issues with it where it had to go back in for warranty work. On many of these faults Triumph would argue whether it was a warranty issue and try to get out of doing the work. Subsequently, i wont do business with Triumph again.
