1985 honda mtx 125 with 200 engine

[funkysnair]

Well I sold my liability of a road going ktm sx200 and found this gem of a old trail bike.
Was sceptical at first as the bike is nearly as old as me but what a perfect example of a bike and I'm sure with some decent rubber on the trails it will be more manageable than the screaming hp of the sx

The guy I bought it off only purchased genuine honda nuts and bolts etc
Most parts are genuine honda apart from the dep

Tank needs painting up and decals but the rest is splendid.
Looking at some metzler 6 day tyres.
If anyone can post up the pics instead of links please feel free to do so I'm writing this on my iphone lol

What you guys think
Cheers

I saw this on the bay and it sounded very interesting. I figured that with a KMX125 and a 200, I really shouldn't though!

It looks fantastic very well restored and I think the MTX200 is another awesome trail bike (albeit a rare one) with a 27bhp 193cc motor full of win and it should be so much of a laugh to hoon round town and trail on!

More pics are 100% required with the tank on!

Yeh mate it's done to a high standard indeed
Couple of weeks and I should have it run in and ready for some trails..
Carb needs a little adjustment as it start to drop revs when it's warm on tick over!

Pulls really well for a old bike.
Hoping to get it mot next week and some decent tyres on there aswell!!

Cost me £1660 in the end once I got it delivered


Cheers
Ken

Awesome MTX .

I've fiited MCE 6 Days Extreme on my MTX 200.
110/80-18 at the rear and 80/90-21 at the front just fits perfectly .
Grip and traction offroad is stunning. Additionally these tires make the bike look even better. Maybe I can find a pic.

I like 6 days but they seem to disappear in no time on the tarmac. I would like to get a two stroke trail bike, rather than endure, something a bit less brutal and a bit softer for pottering rather than encouraging lunacy.

I do like MTX's

I'm having more fun than a well-oiled midget.

Zbraff-I bought the 6 day extreme tyre for the rear also!!
Your mtx looks very nice also-original!

I've installed a cooling fan with an inline temp control
Tail tidy with led brake light
Small bulb indicators
Wrap around hand guards
ordered an acribis disk guard and some fork gaitors

Taking it along for it's first mot in about 5 years today so hopefully I can use it Sunday.... Can't bloody wait

Well I got it through it's mot
Took it out for 5hrs Sunday just gone and it performed flawless I couldn't believe it-solid, comfortable and bags of torque

I took my sx200 on the same tracks and we had to turn around just kept spinning out and was too much of a handful but this little mtx kept going.

Well impressed especially for a 29yr old bike

hi,
is that DEP exhaust a full system? or just end can?
& is it intended for the 125 or 200?
just curious, as i found that when i swapped out the 125cc lump for the atac 200cc engine, best "üpgrades" were fitting the bigger carb intended for the 200 (though im sure the smaller carb could be re-jetted to suit) + fitting a oem mtx200 expansion chamber. (end cans irrelevant afaic)
finding the carb + spanny took a while. try it.

guy i sold it to loved it also, + he used it off road (whereas i just commuted 10miles + went down the odd gravel track)

sill one of the few bikes i regret selling.....

if your ever looking for a replacement expansion chamber, gimme a shout, i forgot to give it to the new owner

cheers,
GAZ

[funkysnair]

Sorry for the late reply

The dep is just the end can and I'm not sure on the expanny although the person who built it says it's for a 200 but to be fair I don't really know

It's running the stock carb with jetting etc to the book.
I've come across a problem well a real big problem

2nd gear is gone

Soon as I knock it into second gear I can't knock it up to third and as soon as I give it above 6k revs it drops into neutral then I have to work it through first then second again then into 3rd
Seems worse when first run (cold)

Changed oil etc
This bike is immaculate and it's not been badly treated basically a freshly built bike

Noticed the bike starts to bog at 7k so in guessing the atac has ceased or not working

At my wits end here
