Your Twin Wheel Adventure Guides We have been riding motorcycles in the Southern California and surrounding areas for more than 40 combined years, and have literally logged hundreds of thousands of miles. We know the excellent backroads, canyon and mountain areas, deserts and coastal routes. Plus, all the great stopping points on the routes - be it biker hangouts or scenery lookouts, and of course eating establishments. Bill 'thumper' Walker Thumper has been riding motorcycles for over 30 years, and is a master at leading groups. He has ridden dirt bikes, sport bikes, touring bikes and everything in between. His ride of choice these days is his Yamaha FJR1300. Thumper knows the best routes in California, including coastal, scenic and back roads. You would be hard pressed to find a better guide for your motorcycling adventure. Thumper's preferred riding style is carving up the canyon roads and pumping the adrenaline. Murray 'joker' Jansen Joker will typically ride as tailgunner for your Adventure, making sure nobody gets left behind or stranded. He has ridden exclusively cruisers and touring bikes, including Yamaha, Honda and Harley Davidson. He's currently found on an 07 Harley Street Glide. Like Thumper, Joker's style is to push his riding to the limit - but is also content hanging out in the back of the crowd and taking in the sights.
