The electrical problem suffered at the Scott by Doug Lampkin is, in this case unique to the "factory" bike he is supplied with. The electrics used on Doug's bike are not items used on production Betas.
The electrical systems are bespoke, as is the motor on the factory bike.
OK, to the general public, it doesn't appear satisfactory, but we are talking about a factory competition machine which is totally different to production machines.
The electrics are designed to run Doug's motor and would probably not work if fitted to a standard motor. The world championship machine is designed to do that job, not the Scott or SSDT.
