thanks for the replies.
The bar was like the Slam pictured on their website,that has tighter radius bends than the smaller Race bar.
Also, both bars are 1/4" smaller than another bar i have. A Radix power bar, that was listed as 5 1/4" rise and so it is.
From top to centre is 153mm.From top to start of bend at grip section is 20mm. Subtract 20 from 153 and you have 133mm.5 1/4"
This is how i measured the DK and Slam also.
The dk's are listed as 5" (on the General Lee spec sheet) and so they are.
If the whole U.K. supply of Slams are like this, i don't want to mail order them to find out.!
