Tigers are "forever" in the shop due to stepper motor failure
Triples are prone to stator and rectifier failure (iirc they had a recall on this, check that your model is not affected, or if it is, that the recall has been done)
Every brand is going to have its duds and the small sample sizes we all have looking at family and friends is not going to give a good picture of reliability. Most BMWs I know of only start giving issues around the 80 000km mark (I know of one thats still going strong at over 600 000km), doesnt mean you should think BMW is ultra reliable. I've also seen a 1200 destroy its timing chain within 1000km
I'm of the opinion that every brand out there today is reliable enough, otherwise they wouldn't be in the market anymore
