Thanks Nevsmile

MIG is the only way i can weld at the moment, I've tried a bit of oxy-acetalene but I'm useless with it haha

Keep with it, it'll help towards learning to do tig, must say I'm old school and gas welding is good all round way, plus I can do it outside too. Though being a Plater by trade stick is pretty much how I roll, I got my coding in low hydrogen stick.

Yeah I'd love to be able to do TIG, looks so nice on un painted ally haha

To be fair, I've only been welding a few months, started messing around with my Dad's MIG just so I would be able to do it at college on the bike.

That's what my eldest gal used to do in my garage, then she did C&G car mechanics at south devon college, and was pretty much best in a class of lads.

Finished at college now, start uni in september so the bike is back home!

It was so hard getting any work done there, only got 3 hours a week and the tools were always missing.

Now that it's home I can really crack on with it!biggrin

This was eralier today, thought I'd offer up the YZF-R125 rims I was planning on whacking on the DT...

Really pleased with how they look, will look even better with the USD front end I've got to go on

But I don't understand. YZ's are as light as anything anyway. Especially modern ones with ally frame, swinger, wheels and bare minimum of everything. I struggle to see how much lguther the TS is?

According to google dry weight of TS50 is 90Kg

Dry weight of a new YZ is 93 Kg.

Surely that's the difference between a big person and a small person. Or in other words fack all.

Yz's are not huge either, and you get the bonus of USD's and adjustable shocks.


Don't get me wrong huge props for the project but I just can't see it being faster than a standard YZ125!

Cheers Toy and David, I'm in Surrey.

Callum, still trying to pick holes are we?

Firstly, I'm flattered you've taken time out of your day to go and research the specs of each bike.

However, this project is all about me challenging and honing my technical and engineering skills, not about spending 6k+ on a brand new YZ.

Where's the fun in that?

This particular engine is from a 91 YZ125 which is a fair bit heavier than the modern ones due to the steel frame etc.

Also, the STANDARD TS is 90Kgs dry, but this will be closer to 80Kgs, on such a small bike 10Kgs is a huge difference.

Power to weight ratio for a YZ125 at a dry weight of 93Kgs works out to be 354.84 bhp/tonne.

Power to weight ratio of this will be closer to 412 bhp/tonne.

Still with me?

The difference in seat height between the bikes is around 125mm, again a huge difference.

For the style of riding I will be using this for (light greenlaning and maybe a few runs at Santa Pod) this trumps a YZ in every way, shape and form;

Lower centre of gravity, lighter bike, I don't quite understand what your getting at?

Maybe you should look inwards, with all the money and mods you've thrown at your DT, how much better does it actually perform?

From what I can tell, mainly only aestetics...

Not knocking you, some people are more into the "image" than the performance and theres nothing wrong with that,

I personally am more into performance than polishing my knobs...

******* POST ABOVE MISSING DUE TO BEING DELETED BY MOD ************

As stated previously, this bike is primarily going to be a greenlane machine; there are a set of alloy off road wheels in the garage waiting to go on.

Not certain what diference the small frame makes to the bike's off road abilities and as for your beloved USDs, they're not necessary.

I do infact have a set of USDs to go on but purely because they came with a disc brake and were on ebay for 20. The fact that they're USD had nothing to do with me purchasing them, I needed a better front brake. They would still be going on the bike if they were conventional forks.

Take a look at the Ossa Explorer. Tiny bike, small frame, conventional forks... but look at what people can do with it.

In real world terms, Upside down forks are mainly an image thing, unless you're jumping the bike etc you can't tell the difference.

After all the time, effort and money you went through getting your front end to fit, can you honestly say it's improved the handling at all? Probably not.

You would have been better off changing the oil in the original forks to a thicker grade and putting in stiffer springs.

That said, it's your bike and it's not my place to question you or tell you how much of a muppet move that really was.

You've completely missed the point of this build.

Why do people modify anything?

Well why not?

At times you can come across like you're trolling, whether that is intentional or not, only you know.

How small is the frame mate? Is it as small as something like an 85 big wheel? You've probably stated it somewhere

Cheers Carlos, I will do mate!
Never sat on an 85 mate but I'd guess this frame is a little bigger (don't hold me to that though).

I'm always at box hill, didn't realise so many people were local to it as well.
We'll have to sort a meet out at the hill and maybe go on down to Brighton or somewhere soon?

Depending how tall/big you are you may be a little limited when offroad, but that would mainly come into efect over jumps etc

Well good luck for the build Smurf, how's it coming along?

And 2stroke, I'm just short of 6ft but with high bars/risers on it won't be a problem

Wickeddd, I'll try and sort one out at some point soon

Just remember the bar risers will raise and bars upwards and backwards towards you, therefore less ****pit room

Thats why, being 6'3, i bought an aftermarket triple clamp with holes so i could mount the bars further forward and upward... Made a hell of a difference
