If memory serves me right, all of the mark 1 Burners with the front two hole gusset were the same frame geometry. They were all made on the same jig as the Chopper, all be it turned upside down, for the front triangle. The forks were very raked on the basic models, this seemed to be the same all through the range except the Ultra Burner. It was only when you got to the Pro or Team burner that you got proper BMX geometry and tubes made from anything but gas pipe.
Raleigh jumped on the BMX craze a bit late, but sold a lot of cheap bikes none the less. They updated the range in 1985 with the introduction of the Aero Burners, oval tubes, but the geometry didn’t really improve. They were still roughly “race bikes” which had the disadvantage of weighing a ton.
Racing had dwindled for ordinary kids, there was still a very big race scene but it was populated by pushy parents and their golden children. The rest of us were riding as most kids did, on any bit of dirt or street we could find. Freestyle was were the cool kids were at. Ordinary riding would later become dirt jumping or street riding.
And they had a larger tyre at the front for extra grip. Well, grip was something the plastic tyres didn’t give you.
