Frankenstein, 1984 CR125 with an 81 XR200 engine

[evo550]

Remember watching Johnny O'Mara on a 125 pass Dave Thorpe (I think) on a 500 on an uphill straight? 

Tony..1986 MXDN, At about 9 minutes into vid shows O'Mara on the 125 hunting Thorpe on the 500 and eventually passing. O'Mara second beaten only by David Bailey who was also on a 500

With Dacka coming in fourth behind Thorpe.
Caught a glimpse of a real Malboro Yamaha as well

An 84 CR125 would have about 32hp. An XR200 has 18hp. It weighs more and the weight is higher up. It would use less fuel and have a less vulnerable exhaust. If anyone can ride a hybrid like this very fast it is because he/she is a very fast rider, not because the bike gets faster with about half the horsepower.

How much and where is the torque in the comparo. I bet the XR has more in a sweeter spot and therefore there might not be much between them on the track.
My only miss giving would be the XR is very prone to wear as mine shits its self too regularly-shit it's fun to ride though
