View Full Version : Fickleness is expensive... building a Super-mono

I am plagued with a curse. This curse is that I will get some crazy scheme in my head and there it will stay and grow and cajole until I either do it, or come up with another, crazier scheme with which to displace the first.

At present, prepping my Ural for overland travel to far eastern Russia is my main distraction and will not be ousted easily given that it actually serves a practicle purpose...for once...

However, a new one popped in this morning: Getting a shagged NS125R rolling chassis and shoe-horning in a second hand XR650 engine!! Am I daft, suicidal, inspired or a combination there-of?

I have always enjoyed Super motos, but I have also, always admired Supermonos!! Decent set of tyres, and a racier chassis::blob3:

Problem is I earn a pitiful wage as a part time teacher in Estonia (precisely 11% of my previous salary in the UK :(). Plus the one time I tried to re-build an engine it did not work! Am I lining myself up for some pain and aggro, or should I have a crack??!?!?

I get your drift about shoehorning a torquey motor into a lightweight 2 stroke chassis, considered the same a couple of years ago with the NSR250 I had at the time (luuuurverly but temperamental!).

It went as far as measuring up my TRX850 motor & considering something like a CB500 motor, ended up ditching the idea as I guess the end product, would never be worth the time/money/sweat & tears put into it!

Goodluck if you go ahead tho

The TRX engine will go straight into an XTZ750 frame with no modification.

We've got a Cagiva super city 125 with a blown up engine (they take the mito 33bhp engines) that we're looking at turning into a small high powered trails bike, the forks/frame on them are fantastic and would really suit a larger motor, we know people who have put in an RD 250 and 350 engines into them, perhaps this might be more suitable for the Honda NSR??

alway wanted a super city......... sexual favours assured if you had one of them and you could wheely past the bus stop! (shame we have to grow up, i think 18stone is a bit past the all up weight?)

how about a strong but not too heavy mill like a xr250/dr350? or go mad with a sv650 twin?

i too have a crazy notion, after coming back from the coupes moto legende. i want a ural/dneiper outfit, the 2WD one because the car and rear wheels are joined by a shaft. you take out the copied bmw r75 motor from the 50s and put in a R1200S motor. paint it matt green or dodgy silver flake so it looks original. but you also put another one in the boot of the sidecar, with a shortened ural drive to keep the gearing. tune the engines together with a power commander and go look for someone to play with

This indeed would enable the Ural's unique handling characteristics to really spread their wings!!

On the plus side, once your contraption had catapulted itself into a tree, the other combo riders are bound to be helpful!!

Ouch, 100+ hp in a dodgy WW2 sidehack frame?

I was thinking about a tweaked R100 motor, that sounds like plenty fun already.

Thenagain, another of those little daydreams is shoehorning said engine in a 2CV and go mess with some of the hot hatch crowd. ;-)

Thenagain, I remember an article in a bike mag sometime mid '90s about the "Rice Guzzi", apparently a completely bone stock looking Guzzi California with a mad motor, and them going out & about trying to lure CBR600 riders into a little traffic light sprint. ;-)

yeah, thats why i want it!! pref with a boxer cup racer engine!

another thing i want is a CX500 cafe racer conversion, saw a few of them at the coupes and they were fantastic pretty little bikes, really well done.

i like supermonos and motos too, a cafe racer rep SRX600 would be nice, but not look as nice as the plastic maggots
