I went to the dunes at silver lake (michigan) a couple of weeks ago and thought it was an absolute blast... except for the fact that pretty much 15 minutes after we got in I decided to climb my first dune at full bore (like hauling ass in 5th gear...) and I well umm chopped the throttle just as I crested it and took a huge dive over the bars Of course I held on to the damn bike until I could see behind me when I hit I broke the flag off the back, cracked and chipped the front and rear fenders, and tweeked my knee so bad I couldn't stand for a few minutes... Afterwards I bought a new flag and we rode for the rest of the day. So, does anyone else ride at silver lake or any other dunes for that matter? I guess I have a question to add to my little story... I need a paddle tire, How many paddles should I get? 6,8,10? what does more/less paddles do for me? And just in case someone happens to know, where in the hell online can I buy a hub for the rear tire? The only place I can find them is on a OEM parts finder and they are 150!!
