January licence purchase the intent was to be racing the 17 year old SV650 only at RACE in BOTT Lite and Lightweight Superbike. So the licence listed the Suzuki.
The Ninja 300 was a last minute decision. (he rode for the first time the Thurs before Round 1). RACE doesn't list multiple bikes for the same rider in different classes. CW results list YAM for his bike in the BOTT class when he is really on his SV650 since he listed the R6 when he bought the 2016 licence.
