I've decided I want to replace the grips and the bar ends on my VTR250. Im new to all the terminology so laugh quietly if you must. I looked on eBay and noticed that most of the grips were for the Gixers, CBR's, and R1's, R6's. Are there different size handlebar grips and if so does anyone know what size for my bike? And also do you need to purchase bar ends seperately? Is it an easy job to replace these parts and what is involved? Many thanks for your time and advice.
