I have had 19 motorcycles and have been using "Lemon Scented Pledge" (buy it at Target or any store) on every one of them... I just cleaned my whole bike (08 R6 -frame, Wheels, swingarm, forks, plastics, windscreen etc..) and it shines awesome and works great.. Try it and you won't be disappointed
I only wash my bike when its really dirty, than I use soap and water with WD40 on the wheels.. after washing it I use the pledge and finish it off.. Usually after every ride I spray the pledge and wipe it down.. It works like Plexus does only better IMO and cheaper to boot..
I take my bike to the coin-op car wash every Sunday and then finish it with Maguires Spray Wax on my entire bike except my two brothers can. I do this for two reasons. The first is that with the wax the dirt and grime especially bugs (from canyon runs) will sit ontop of the paint and have a less chance of scratching the paint. Second because it looks so damn sexy when your bike is clean like that.
I highly recommend maguires products. There is no reason to skimp on detailing supplies.
