Unlike the older Yamaha 600s, the DR Suzuki is more robust, simpler and less likely to throw balance weights...that is why I bought mine. Afer many, many adventurous miles, the only problems I´ve had are with the pickup coil on the pointless ignition and finally...an inlet valve thru the piston. So now she is sitting on my porch waiting to be repaired in time for the great over 50s mountain kingdom trip. See www.madgodcomix.netfirms.com
