DATE CHANGE!!!!!    November 15th  – 47th Annual Hansen Dam Rally

Get those beautiful bikes ready and attend the largest Classic Motorcycle event of the year in Southern California!

Due to unforeseen circumstances, we’ve had to move the date to Sunday, November 15th.  Our Hansen Dam event will once again feature a peoples’ choice judged motorcycle show this year. Those that want to participate will get a numbered hang tag for their bike with “year/make/model” written on it.
All spectators will be offered a judging ballot & a pen.  Ballots can be turned in at our club awning.  At 9:30 am we will start tallying them up, and at 10:00 we’ll have an awards ceremony.

We will have trophies for the following classes:

Best British – 1950’S
Best British – 1960’S
Best British – 1970’S
Best Modern British
Best British Custom
Oldest British Bike
Best Non-British Bike
Best British in Show
Best Norton in Show
