Just a random idea that popped into my head! Smile

I was looking at a photo of an old 1990 Kawasaki KMX and while beauty may be in the eye of the beholder I think it was a lot more practical than aesthetic in design. Are there any bikes of that kind where the tank, seat, plastics etc might be easily replaced with earlier (70's/80's) more curvy looking bits?

Problem is that the 80's/90's dirt-donks were so often water-cooled and MX inspired.

If you look at the air-cooled bikes without the radiator cowlings and 'stuff' you have a better chance.... but they are mostly four-strokes.

BUT for the sake of... why bother?

If you want that 70's 'retro' look, why not buy the 'real-deal'?

Plenty of older air-cooled mud-plugers out there, and they have lots of virtues in simplicity and are very useful bikes...

Not so great over whoops and burms, but how many of them do you find on the average country road or green-lane?

I've always liked the 70s dirt bike look, but some of the prices are getting a bit silly now. Nostalgic individuals seem to be lusting after certain iconic models. So it would pay to do a bit of research and maybe find one of the less "sexy" models.

If you want a cheap air cooled trail bike project with more retro styling and twin shocks etc, then i would look at very late 70's and early 80's stuff, mainly the bikes that were replaced by the new more trick MX styled watercooled stuff.

For example a Suzuki TS 125/185/250ER or a Kawasaki KE125/175 would be good choices in that they don't have the looks of the prettier and much more expensive early 70's stuff, and yet there are unwanted and unfashionable compared to the liquid cooled mono shocked next generation bikes.

My only other advice is, I would probably steer clear of Yamaha DT's even the late MX models, not because they are not fantastic bikes, but Yamaha has become the most sought after marque for anything 2stroke, and as such prices have rocketed as more people want to buy up classic bikes for resto's etc.

The same kinda applies to anything Honda and XL/XR, as they were for a good many years the only 4stroke trail bike option, and as such they are nearly all sought after and priced accordingly.

of course the main motto for any resto project is that you should pick a bike that you really want to own/restore, as if you just look for a machine that is not sought after, not popular and or is just cheap to buy, but may have never been a great bike, then you will probably get dissalusioned and lose interest before you get very far into it.

Some folk will say pick a bike that is and or was very popular, and one where the NOS, re-manufactured or aftermarket parts supply is still very good. There is merit in that argument, but not at the expense of rule No.1

The main problem now is that there are lots off different generations wanting to re-live their youth and buy into their past bikes again and can afford to do so, so really although the appeal is different to different people, there is overall a strong interest in bikes from the late 60's right up to the early 90's as possible restoration projects.

Maybe now is a good time to start buying and re-building cheap 2000-2010 Chinese trail bikes, before another 10-15year's when the kids that had them as learner machines, all want to re-live their first bike times again.

The world is mad, spend £3000 restoring an FS1E? Who knows what people will be spending on Lifan and Jailing 125's in 20 years? Wink

Well the DT-MX models were cantilever mono's, not T-Shocks, which makes them a bit more esoteric. The very first factory mono's they have a 'long' De-Carbon' shocker up the back-bone, which is nie on impossible to get a pattern replacement for, but not a project stoppa.

Personally, I went for the DT BECOUSE its the popular choice, and because once done, prices MAY be better, so justify work & parts going in to it, WHILE being the more popular new, and used, and as projects they ARE the best supported and easier to get bits for.

That tad extra up-front, you might have if spend being off-set by 'savings' later down the line, in hassle if not cash.

The small bore DT's DT100 & DT125 BTW were twin-shock right up until the DT125LC came along, and I think the DT100 stayed in the line a few years after, that in '82, until superceded by mono-shock DT80MX, bored out version of DT50.

The Twin-Shock DT's aren't commanding SUCH 'classic' prices at the moment, but prices are rather random.

DK are asking £900 for a DT125E T-Shock needing restoration; one sold on e-bay last month for £799, ready to ride, part restored. There are dealers asking £2K_ for original unrestored or fully restored examples, and folk struggling to sell well renovated bikes for over a grand.

If you want a fixer-upper, and are looking at old field bikes to do-up as a project...... my DT cost larger chunk of £1500.... you can get something pretty 'useful' ready to ride for a lot less....

And if you want a 'budget' classic T-Shock? I think I would be hunting out a DT100..... not test eligible as a learner legal these days, most parts shared with the 125's but less popular.

Seen some nicely restored DT100's going for relative penies, ready to ride. Its an RXS100 with 'attitude'! Ie a 'safer' model to plump for.

Thanks Mike, insightful as usual. Thumbs Up

I hadn't really thought about how different twin-shocks and radiators make a bike look compared to a mono-shock but it's obvious now I think about it.

I wish I'd bought that old DT 175 MX when I'd had the chance; why is it you can never appreciate a bargain when it's staring you in the face? £300 for an easy fixer-upper.. what was I thinking?

TM don't get me wrong, id absolutely love a DT175MX. I think they were the best clubman's trail bike and most versatile machine available in the late 70's early 80's. In fact until things like the TS125X/DT125LC and MTX125 came out, they were probably unbeatable in terms of being a decent road legal small trail bike, yet having most of the off road ability of things like an IT175 or PE175 proper enduro bike.

I love the engine as well, as it's the same lump with minor changes as was used in the TY175, which i owned one as a school boy trials competitor. I used to love the sound of my old TY and having a DT175 would bring back so many memories, but mean id have a useful machine on the road as well.

The reason i suggested things like the TS185ER or KE175 to the OP was that they just don't seem as popular, or sought after as the DTMX. That also means they are like for like often much cheaper, and dare i say it that either bike is no where near as good as the DT. So that means you should be able to pick up a fixer upper or resto project for much less cash, but whether you would end up spending more or less to do a nice renovation to the same std as your DTMX was, is difficult to say?

I don't fancy finding some parts for a late model KE, but then if the bike is cheap enough to start with maybe it offsets some of the difficulty and expense in getting parts for a resto? I really don't know TBH, but i can understand the logic for picking a popular bike with good parts support. Kawasaki parts support is probably the worst out of the big 4 by a long way, but if it was a bike that you really wanted, then i would still choose the bike i wanted, over the easiest one to restore or get the bits for.

I'm going to keep my eyes open for both the TS and KE, they're both interesting. I've seen a few TS 185's on Ebay but they've all been field bikes and tbh I'm scared of anything to do with replacing fiddly, complicated electrical bits.

On a side note, I wonder if the price/value of small bikes will go up next year with the 47bhp restrictions encouraging sales of smaller, lower-powered bikes.

Echoing more than the 'sensible' reasoning I got my DT Laughing

Yeah, we had the same reasoning to different conclusions. Only thing is, as I've found you ALWAYS end up spending more on a project bike than you anticipate, and starting with a bike that's less common, and worth less when done, usually proves more expensive in the long run.

Why I suggested the DT100E, as a compromise.... much under rated little bike, nie on the performance of the T-Shock 125, but loads cheaper to buy..... not as valuable 'done' BUT with the DT support and compatability with so much DT & TY 'stuff' a less challenging place to start!

This is the problem; old dirt-donks dont die and get laid up, they get thrashed round fields. Syuff gents botched and bent, buitchered, mangled and anything non-essentiual chucked in the bin, and the electricals are first thing to usually go.

Have a look at the TY's Steve mentioned...... they are quite a useful little bike,m and with standard solo-seat, not wonderful road bikes, but still very capable green-laners and round townie bikes, and not much loss compared to a DT100.

BIG plus in added capability that they are a BRILLIANT trials newbie bike, and very popular for classic T-Shock competition.

Ie do one, and it can have added functionality, going trialzin.

With solo-seat you can get them Day-Time MOT'd with a pp3 powered horn, number-plate and speedo.

You dont HAVE to have full lighting kit, if its only a toy....

If you DO want the full lights, like I did for my DT.... well the electrics are pretty simple....

One wire from the mag to the coil for sparks..... then probe any extra wires from the mag to find the lighting coil.

You can buy 'lighting kits', which are basically headlamp & tail lamp, and a pair of switches, one handlebar switch for 'on-off' dip/main and a stop lamp switch for the brake lever.

Come with 'loom' and two wires to put to 6 or 12v battery.

Thats what I used on my DT50 umpety years ago..... and if you cant fathom the charging system, you run it 'total-loss' off a battery, and just charge it up at home.

But, DT gennies are pretty good, and common 12v conversion using a pit-bike regulator. My DT had DT100 mag and delivered enogh volts and amps to charge 12 DT125LC battery......

Simplified electrics in you take two wires from mag, one for charge and one for direct lights to the regulator and then just the one output straight to the battery, job done.

Its not too difficult, but something you WILL undoubtedly have to tackle IF you want to do an old dirt-bonk.

And you know where we are if you need help1
