Picked up this old grasstrack bike the other week and it’s quiet an interesting piece. Apparently built in 1960 by Don Smith but not sure if this is fact or fiction. I know nothing about these things but seems to be a Bantam based frame which seems to have been fairly common? It’s fitted with a 2 stroke Villiers which seems to be very oddball indeed! I belive it’s a 200cc but not sure 100% It came with the west ham vest as Don Smith seems to have raced for them early 60s but no idea again if the bike is or is not related to that!

Of any of you guys know anything grasstrack please enlighten me it would be appreciated!

Cool as How many gears?

Hey Chris long time! Hope all is well! It’s a 4 speed box in it. Has brakes too which is unusual but seems more common on early ones? It’s super cool. I’m just not sure now if I sell it or put it on a shelf in the garage and look at it! Won’t be trying to get it sideways nowadays for sure! Lol

Doing ok thanks Lee... the number on the top of the case doesn’t seem to ta with anything on this list Are there any other numbers anywhere? it’s an interesting bit of kit

I had a scan through that list too and couldn’t match anything. The only other number is on the front of the crank cases but very hard to see with the engine being so close to the down tube.

From the other side. Seems to be D73B
