She`s a heavy old beast fuelled up though over 700 lbs!
I doubt whether there would be room in a TRX chassis for that motor,check how tall it is from top of head to sump bottom.
Mind,it might fit inboard of the frame rails.If it does maybe it could indeed be done.It`ll also need a different tank made up as those injectors would clout the underside of the TRX tank.
I agree,a cafe racer version would be lovely,Norvin type of thing with double the torque,mmmmmm very addictive. :wink:

DR800`s?
Yes I would love one,105 mm piston that`s over four inches across :wink: and a shade under 46 ft-lb of torque at 54 bhp(that`ll be at the crank though)!

Saw an MRD framed DR800S go very well in the past.
Getting rare now too. :wink:
I can take my Skorpion to 760cc(104 mm bore)by stroking the crank but on a stock motor the max is 720cc.

Capacity and torque is a good measurement of how well the engine's tuned. In EUROPEAN (non-British) standards 1 Nm /10 ccs is OK, more is good. Now take a look at yesterday's TRX competitors, like the 900 SS :) Obviously, modern engines burn fuel much more efficiently though...

Also shows that peak figures aren't the whole story (by any means). IIRC the old pre-FI 900SS had a torque curve like Ayer's Rock, while the TRX comparatively speaking had a very weak curve under 4/4,500rpm. Yet the peak torque figures are close, as you'd expect from engines so close in capacity and CR.

The TRX also lacked exploding head studs and a sui-cide stand, and substituted functioning warning lights for the randomly flashing fairy lights on the Ducati's dash. Where did Yamaha go wrong! :lol:

You really want to know?
In my opinion by fitting cheap forks,seriously undersprung and underdamped.Although the TRX package couldn`t possibly be termed `wrong` it was compromised by Yamaha`s penny pinching.
Why they couldn`t have fitted the YZF forks and possibly brakes too as stock must only be down to budgets,after all I can`t imagine the cost differences to the factory being massively different.I think the design team and engineers were given too stringent a budget to work with myself,a little more free reign would have produced a TRX stunning in every aspect,a Ducati beater on all points. :wink:

It's just JDM syndrome. Japanese vehicle manufacturing relies to some significant degree on high implicit barriers to imports combined with import substitution. When foreign vehicle manufacturers produce a desirable piece of design or engineering, Japanese consumers are not able to buy it due to the huge barriers to entry into the market. If demand warrants it, a rip-off will be produced. So in the last ten or fifteen years, to take but three examples, they've done Volvo 850s (90s touring cars), new Minis and new Beetles.

This sort of makes sense given that the Japanese are the ultimate commodity fetishists - fashions and fads spring up somewhere near Harajuku and last about 20 minutes, during which time they're ruthlessly commercially exploited (usually because the people selling the product created the fashion or fad in the first place).

If we set the OVER bikes aside, the TRX was designed at a time when Ducati was newly-resurgent after the 4-valvers Raymond Roche and the 888, there was a corresponding interest in twins 'period' due to the spanking 4s were getting in WSB and there was a burgeoning interest in retro biking. If you look at the JDM TRX in profile (red *cough*), you can clearly see 851 and 900SS CR. Unlike the VTR or the TL (or TL-R, or RC51), which were machines for the speed-addled export markets of the US and UK (and western Europe, to some degree) the TRX was designed to sell Japanese consumers pseudo-eyetie twin-cylinder retro-framed motoring to suit the tastes of the moment.

IOW, the TRX wasn't designed to succeed as a bike, it was simply a place filler for the 851s and 900SSs that the Japanese couldn't get hold of (for less than a fortune). Which explains why things like suspension, brakes and tyres were left out of the equation. And arguably the engine, since they simply robbed a design based on the 80s-tastic XTZ. OVER again notwithstanding. It was then thrown into the export market because Yamaha couldn't or wouldn't invest time and money in a performance twin (having just started out with the YZF750), but needed to have something to sell when the UK market was mad for twins.

Hmmmm,yes I agree,forgot to even consider their home market. #-o
And that Japanese `fad` stuff,bl**dy shame it doesn`t seem to apply to Poke`yermom and Hello Kitty!
I detest all that naff Japanese junk,cartoons and merchandise:

WTF!!!!!!! :shock:
I would love to make Sanrio the company behind Hello kitty go tits up in a big way,and their products be incinerated,never to be seen again. :twisted:
I wonder if any saddo has a TRX in Hello kitty colours? [-X
I wouldn`t be surprised if at least one motorcycle exists in Japan.
Yep.found it:

There`s probably a Hello Kitty themed pavement pizza out there too Steve,in fact it`ll likely be brought on by over indulgance on this:

There's lots of stuff that was missed out on when they threw the TRX together. The Thundercat uses the same top yoke as the TRX and it's a common mod to use a TRX ally bottom yoke in place of the cast iron T'cat one, saving nearly a kilo. The TRX could've had the rwu adjustable forks and blue spots off the T'cat, but then savings were made on the T'cat by using steel rather than ally for the frame and swinging arm. Maybe the joy of TRX ownership isn't the overall package that Yam gave us, it's taking that package and making it your own ;) I love mine, cos even languishing in its current untidy, bouncy-forked, oil-guzzling state it's still a really capable and enjoyable bike to ride, and the sound is just ossum.*

I am going to buy a pair of those and put them on the wife's Clio 182 without telling her. Oh yes. It must be done.

You`ll have to leave two saucers of milk behind it every night,you do know that don`t you? :wink:
Ferkin Hello kitty stuff,it`s all Sanrio shite in my personal opinion.There`s all sorts of stuff jumping on every bandwagon that exists,it sickens me to the pit of my stomach! :(
