...me me me!!
102hp on the rear and 154Kg on the road (with fluids)...that would do it for me!!

Well at least one of our members has a direct line to an `ex` Spondon man.
It`s a thing of beauty for sure, but wouldn`t be cheap sadly.

Some serious money spent there - I want that carbon tank and body work. He can keep the SSSA though.

I have my doubts that that weighs 154kgs fuelled. 4 litres of oil, 1.5 of coolant and (only) 5 litres of fuel weighs well over 10kg and there is no effing way that is 140 ish dry.

Id agree - mine weighs around the 160 mark (dry) & can't see how another 20+ kg's have been saved on this one.

Nice bike tho - wouldn't say no to it being in my garage between the NWS bikes

Anyone know how much just the trx engine weighs?

70-ish
Really can´t figure out why the bloke would write 154kg on his website if it was not. But hey, we have all the TRX experts in here!

Cast ally engine cradle +swingarm + rear brake caliper, rod and M cyl =10.9kg Not got a spare engine so cant weigh it!
I wonder what the VFR(?) swinger weighs? and the spondon frame incorperates the cradle part so must be saving a little there.
Forks look quite trick too

Very nice bike, but is it still a trx?

Just had another look at the swinger! NOT vfr ...maybe just a vfr wheel?

That`s Spondons own swingarm in there Cal.
You can see similar versions of them on G.I.A`s site:

Gavin used to work for Spondon.

Edit:

Of course it`s a TRX it`s `heart` is that lovely parallel twin motor.

I'd say a bike has to have a bit more than the engine to qualify it as a TRX (or any other bike for that matter), dont get me wrong though, I think the spondon is a very tasty bike and still has somehow managed to keep the look of a trx, I wonder if the geometry is the same, wheelbase, headangle to give it the same feel.
102hp at the wheel! maybe one day!

We could play spot the difference with these two pics, I know there was a few spondon frames made for the trx but i'm sure these two pics are the same bike, even though there are a few differences (top fairing, seat, tank)

It looks like the engine sits a lot higher than standard... That could just be the perspective though...

I'm not sure that I like it overall...

Cal, you are so missing the point here - at what point does it stop being a TRX? If you fit a 2 into 1 system is it no longer a TRX? If you change the rear subframe or bodywork is it no longer a TRX? Different suspension no longer a TRX?

If it had a TL1000 motor chucked in it i'd agree it's no longer a TRX but the character of the TRX has always been the engine itself. As a standard package the bike as a whole is a mish mash of old Yamaha stock bolted around a redesigned engine (well, crank actually) which actually worked 'reasonably' well but was always going to be & is a complete 'blank canvas' for special builders who saw much bigger potential for the model than Yamaha did?

If you are happy with 'reasonable' that's fine too

It's actually because the lower frame rail follows a narrower taper than standard using the top rail as the main structural member - note absence of any lower rail above engine rear area. It passes behind the main structural member to support the rear subframe. I think it actually has a nice open un-cluttered look about it. Other reason for engine looking higher is the oversize tubing used on the top rail - visually it will give that impression due to the open space being taken up with.... more tube

Point taken about the trx engine being one of the main characteristics of the bike, however, unlike yours, the frame its not even similar to a trx, it is a totaly new design, swinger new design,body work/fairings spondon?, forks? dunno but not 41mm rwu!
I do think there is a pont where it stops being a trx but where that line is, is vauge. In my opinion its crossed it, thats not a bad thing its just evolved!
If you were to put a tl 1000 motor into a otherwise standard trx I think you could still call it a trx, if you put that same engine in the spondon, then its no longer a trx, its a spondon tl1000
Maybe this is more an attitude from hotrod upbringing where different engines no matter how special made no difference to the name of the car.
I am always learning and being surprised about how much the TRX is a different bike than most and the following it has.
I got mine almost by accident for very cheap from a freind who wanted it out of his garden, I had no idea about the bike at all, I got it started by towing it with a truck, heard the noise from it and fell in love
As far as reasonable goes well I'll have to settle for that for now until the money tree grows in the back garden. But when that tree grows a bit

When the tree grows a bit i have a garage full of very nice 'make your Rex better' bits i'll be selling soon - including a 'one off' NWS aluminium rear subframe which accepts all standard equipment! As well as a Maxton front end, YZF750r front end & a very nice mirrored T.ace swingarm c/w wheel
