So I need a whole bunch of wear and tear items for the 06' DRZsm and was wondering what you all recommend for the categories. I'm mostly a smooth street rider, but tend to get off the road and into the ruff for short periods of time on a nice weekend ride. So I'm looking for long lasting milage products but which can also with stand a beating. Chain: X or O (ever hear of Primary Drive? good/bad) Brake Pads: EBC (good/bad) Tires: Contiforces 160/60-17's for the rear! Oil: ??? whats the stock oil 20w-50 (non synthetic or semi?) Oil filter: K&N spark plug: NGK Iridium? Hope you guys can help gotta get a list together and find the lowest prices with in the next week or two. Thanks for your time!
