Ask Leebex, he had one for a short time, he didn't like it

Others may have a different opinion.

My brother has one and really likes it. They were never very popular over here (he's in Australia) so they don't come up all that often and not that many people have first hand experience of them.

I like the idea of a Japanese made Ducati, but they aren't really any quicker than an SV (they make about 80bhp and are 20kg heavier than the Suzuki). Known to suffer from crank problems if not looked after.

Use a bit of oil .watch out for water pump seal

[squirrel_hunter]

Not ridden one properly, but I do like them and I have considered the purchasing of one on many occasion. Though it would have to be the faired one, in blue, with a gel seat.

I think its a marmite bike. You won't know if its for you until you try it. A mate had one and loved it, another mate had a go on it and thought it was dull.

They do start burning oil after not all that many miles.

[leebex]

in the real world it is quicker than the sv! noticeably so, very tall 5 speed gearbox, which is horrible in town, but on fast twisty sweeping roads that's where it feels at home.

I fitted a pair of renegade cans to mine, easily half the weight of the standard cans, and with its firing arrangement really did sound like a ducati, except it didn't have a rattly clutch.

good on fuel, (used a bit more than the sv but that may have been my throttle happy hand and it did sound superb) more comfy than an sv and very good a high speed cruising due to the tall gearing. multi adjustable suspension, but the bikes do feel very dated, even compared to the curvy sv I had before it, but at the time I felt quite proud to own a fairly rare beast.

Best lookers are the red framed oneswith white bodywork, popular mod it to change sprockets to give better gearing.

Oil checks are bit more complicated that usual due to the separate sump so needs 2 stage checking.

decent space under the pillion seat, and the riders seat is easy to remove, use the key on the pillion, then a lever to pull up the riders.

Id recommend one only if you don't plan to use it through town every day like I did, but then the journey I do is more suited to a 250.

unfaired are fightered or crashed ones, this was mine:

I've always liked the look of these, used to see one regularly which had loud cans on.

Quite like the look of the szr660 as well

Friend of mine had one, I had a ride one time. I thought it was a bit agricultural, lots of vibes and didn't rev very far. My friend rode my stock curvy and thought it had better forks. You could give it a go, some people like them.

Good morning all.


As said, they are prone to using oil, as their TDM cousins do. A lot of engines have suffered crank damage beacause of it.

Valve clearances need doing earlier than Yamaha state. They're prone to closing up. Bad starting from cold is a sign of this.

A lot of TRX's got Dynojet kits, & loud cans fitted. Dynojet kits are the quickest way to wear out the emulsion tubes in the carburetors known to man, (short of filing them). A carb rebuild is expensive, & the consequent pre rebuild rich running won't have done the engine bores any good.


Cheers.

in the real world it is quicker than the sv! noticeably so

That's because you have one of those sluggish curvy machines ;)

[maviczap]

Think you'll find he downgraded to a Pointy ;)

How so? I've got a Dynojet kit on my curvy from when it was set up about 10 years ago. Should I be looking at it again?

yes lee has a pointy now.

Its a well known problem with the trx, although Ive not heard about it for other bikes.

And yes, the trx I had was quicker than my sv. Most noticeably when I fitted the lighter renegade cans, they improved the midrange greatly, so overtaking and pull uphills etc was better.

When I compared the weight of the standard cans to aftermarket ones, the standards are insanely heavy ;) and seemed to strangle the bike too

Worn emulsion tubes are pretty common on bikes that have been Dynojetted. I suspect it's to do with the fact that the Dynojet needle is of a different profile to the original. Therefore doesn't match the profile of the emulsion tube, in the way the original needle did. Also, the material Dynojet needles are made from may contribute, it certainly seems a touch rougher that the original needles.

Dynojetted bikes almost always use slightly more fuel from the off, irrespective of who fitted them. Is this a good thing? I think not.
As stated, TRX's/TDM's are amongst the worst to suffer 'post Dynojet' excessive emulsion tube wear. Followed by Exup 1000's, Bandit 1200's, & Firestorms.

A steady increase in fuel consumption over a considerable period is hard to notice. If your spark plugs are on the darker side, &/or the end of the silencer is a little sooty then I would suggest that you inspect your carbs, & go from there.


Cheers.

Thanks for the info. I haven't opened the carbs up more than once since then. Yeah Dynojet do like a rich midrange, I'm told this makes some bikes like the R6 snappier. My mpg dropped from 60 to 55 but it's been the same for years and I don't believe it's running any richer than it was, hard to say over such a long time though.
