I like hybrid's, but it's obvious here that he gave up trying to find a water pump cover for the CR and went with something that has parts in abundance.
My hybrids have all been a necessity of budget...
First was an RD350A in a YZ frame followed by an XT500 in the same frame (road licensed too
)
Second was an XL185 in a RM125A roller
Third was a RZ350 in an RG250 roller (both aquired by insurance auction)
and.... does a TS125 powered steel bathtub/trike count?
