1992 Crisp Mean Mother

Extremely rare Australian made CRISP frame and forks.

CRISP was founded by the Crisp family and raced by 80's Australian BMX champion Dean Crisp.

The CRISP 'Mean Mother', make and model respectively, was my first true racing bike that was bought brand new and custom built in late 1992. The CRISP make was quite popular in the mid 80's through to the mid 90's.  A few people in my club raced them including the 40+ cruiser Australian champion.  I found a photo of him racing his sons 20" CRISP race bike.  It is very similar to the one featured here except it does not feature the connecting bar (read on for further details).  If anyone does have one please contact me as i would love to get another.  The attached photos are the only ones i could find and it is a pleasure to show it.  Take note of the main feature which is a connecting bar from the top of seat tube to the middle of lower bar. It is very similar to the early 'profile' frame set up except the CRISP connecting bar was much thicker in diameter. The 'Mean Mother' decal sticker is featured on this part of the bike.  The paint scheme in picture is original and was metalic black except for the forks and rear quarter which was chrome.
