Like any machine there plenty of things to do , its a question on how much do you want to spend , what your needs are? On ours we put a longer link at the back to lower it a bit , I revalve back and front suspension for more plushness , that's all we done at the moment , but I would put a oversize disc , 22mm offset clamps even lower the radiators with a kit , than if your all cashed up a splash of ti bolts and shock spring to lower weight is a good thing, tm design chain guide and slider as these models wear them out pretty quickly , they even make light weight seats , these things make it better , leave motor mods last as these thing have a good engine for most people , you need good handling and suspension first , no good trying to get around a track if you cant turn or go over a rough straight fast.
