Other than the colours and graphics, and the seat having changed slightly (getting some coloured stitching to match the paint scheme), there’s really very little difference between the model years.
The main two differences/changes to be aware of are with the regulator/rectifier and the crankcase breather.
Some (but not all) of the early T�n�r�s from 2008/2009 (11D1 and 11D2 models) suffered from the regulator/rectifier connector failing and causing no charge and flat batteries. The general consensus seems to be that the connectors weren’t snapped home properly on assembly, whether that was the dealers fault or the factory’s fault is debatable. Those that failed within warranty were replaced (reg/rec unit and loom), but the replacements fitted have exactly the same part numbers so are probably unchanged – just better fitted? Many of the early bikes have shown no sign of this trouble (mines a 2008 and everything is fine still). It is probably now safe to assume that if this connector was/is destined to fail, it would have done so by now anyway, so not so much of a worry with second hand 2008/2009 bikes. If it does fail, there is an easy and cheap fix available using an FZS600 rec/rec assembly and a bit of soldering.
The crankcase breather baffle chamber was modified from 2009 to reduce the amount of oil blown out into the airbox/breather drain hose. Again these could be replaced on 2008 bikes with the new part whilst under warranty. Some people had them changed, others didn’t. Mine still has the old type breather and it’s really not a problem emptying the drain hose and it only backs up after a long ride a relatively high engine speeds. The improved part is the only one available now and isn’t expensive, just a bit of an arse to fit.
In a nutshell, there’s so little difference, you’re aim should be to search out the best one you can afford in the spec you want, regardless of age. Mileage and how well it’s been looked after are probably more important factors to consider rather than age/model year.
