He made 3 of them from differen erras
Usually rides one to the BSA nationals and trailors to the All British Rally ( latter this month ) and to the BSA internationals ( as he bings several bikes to thoose ).
Done a couple of laps of the Newstead grounds on all of them because Doug is a gentleman in every meaning of the word and very happy to share his bikes with almost anyone if he is not relying on it to get him home .Which even extends to me .
So if you come to the BSA international In Hhandorf Adelaide latter this year you could have a spin on it too .( might be a long que though ).
This was the first one
https://www.oldbikemag.com.au/doug-frasers-empire-twin/HE did an electric start Gold Star that he did for his other half before he did that B66 which she rides more than the GS now days .
Note the Empire Twin sits in an almost std M20 frame & drives through a std 20 gearbox .
And for those wanting a better brake for their A 10's note the brake description of the Empire Twin
Doug is also responsible for putting a BSA Fury back on the road and he regularly brings that to ABR's as well but I am yet to toss a leg over it as the que is very long .
Nothing odd to see it pass me 20 times in a 50km ride with a different pilot every time .
