Hi mthee, A CB400SS is basically the same bike and spec as a CL400... Albeit a little better endowed cosmetically. It has a 4 valve RFVC cylinder head, 29 hp, ( taken from old XR400 trail bike ), It differs from my CL400 in that it has an electric start as well as a kickstarter. There is also a rev counter, and both clocks sit in rather tasty chrome surrounds. The two exhaust down-pipes are siamesed together before entering one exhaust on the right hand side. It's not a "powerhouse".... think of Royal Enfield performance and you will be quite close. Seating position is bolt-upright, so no sore wrists... Spares have never been a problem... 60 mpg, and very .. very comfortable,BUT..... PLEASE BE AWARE.... These bikes are for the Japanese and American markets... Mine was Japanese. When imported the two front indicators were on with the ignition and headlight. The supplying dealer had been "into" the wiring with a certain degree of ignorance and naivety... leaving the indicators flashing at about 300 mph..! Fine at a standstill, or MOT time, but not good at real world riding speeds. Not an insurmountable problem to fix, but one you should check out before you part with any hard earned funds..... Any questions, please give me a shout... If you lived in my neck of the woods, you would be welcome to "try before you buy" ... Regards, Tony Calleyne
