Frame Facts: The ET (Original) and KYZ (High End) used the exact same frame, and the ET (Replica) and KYZ (Low End) used the exact same frame.  Put a raw metal ET beside a raw metal KYZ and the geometry, weight (+/-) and quality are the same. You will notice the welding differences at the bottom bracket area.

Gusset: Gusset has either a) a small hole on the right side next to the big hole, similar to the KZ-1 and KZ-2 or b) no small hole on the right side next to the big hole. The KYZ’s without this small hole and are debated as being leftover ET’s in chrome which is NOT the case. KYZ’s with no small hole were made all through out 1982 and 1983 alongside the ET. And ET’s were made into the early months of 1983.

Versions: We have witnesses 2 versions of the KYZ – a Regular size and a Small size. When compared side by side, the Small size has a smaller geometry than Regular size with a shorter rear end similar to a Diamondback Silver Streak when compared to a Senior Pro. The Regular size has a standard size geometry similar to the KZ-1, ET, Nova, and Laserlite.
