I've always loved the look of 1980's superbikes, the type that Eddie Lawson, Freddie Spencer and other rode. Looking at the ZXR400 that JB posted up in another thread it looks so tempting to bin the engine and replace it with a 250 2T motor.

Even more fun would be a TZ750 engine in Z1000 or CB750 running gear

Pointless and probably heretical to do it, a modern bike being so much better in every way. But what larks it would be doing it.

My ZX6R could probably be improved immeasurably by sticking a running 250 2 stroke engine in it. The only possibly fly in the ointment is that further improvements could be made by using the rest of the original 250 as well..

Motorcycles are metal and plastic. We may have a personal attachment to a particular make or model, but each one of them is just a thing.

If you buy one and cut it up and someone else doesn't like it, fuck 'em, they should've have bought it before you did.

I've never cared for 2T's but if it's your bag, knock yourself out.

And just be confident in the knowledge that no matter what engine you build into what frame, it'll never be less appropriate than this.



Yep, it is indeed a 50cc 2 stroke cruiser.

"I've got a Ducati Panigale 1199 R engine that needs a new home, I know, I'll put it in the Grom !! "

I know a man who is in the process of putting an 800cc inline 4 two stroke (two big bore Banshee engines joined at the hip) into a GK76 GSXR400 chassis, the engine is in the frame and he's onto finishing details.

I used to know someone with a 1428cc 1978 Z1000 with a turbo and nitrous, it made 236bhp, the only chassis modification was a 3" extended swingarm

I know of someone with a turbocharged Fireblade engine in an FZR400 chassis, apparently it wheelies.

For some unknown reason the 1982 Z1000J I bought as a big cruising round on bike now has an 1170 big bore, gas flowed Unitrak head and flatslide carbs, and the whole bike has been on a serious diet, I sought of got a bit carried away once I found the flowed head.

Have you seen a Fantic Chopper https://www.bikesure.co.uk/forever-bike ... back-dead/
The 125 had the engine straight out of Fantic's 125 Enduro bike of the same era, someone I went to school with had one, it was mental, an evil handling pig with a very nasty little engine

Ain't nothin' wrong with that.
