Done 7000ks on my 07 senna so far no dramas at all. How the radiator is prone to cracking ive got a bracket that supports the left side so no dramas there.The hub if you look after it properly it wont fail if your worried about it you can buy a mitch hub for 1k,waterpump cause they run hot around town due to them retard the timing so much you can go to a aftermarket moto course pump for 1k.Or put a manual switch in for the fans so you can turn them on early. I just did those things as soon as I brought it cause I didnt want any dramas.
