Honda MT 125 KO 1974
« on: December 04, 2020, 09:33:19 PM »
G'day viewers, it looks like I've got myself a ruff looking Honda MT 125 KO.  Are these a good dirt bike and what should I look out for in its clean up and making it serviceable scrambler again ? Thanks jimson

I had an MT250 as a young bloke. The Yamaha, Suzuki and Kawasaki Two strokes were quicker. They weren't very popular.

the honda mt series handled much better than the other Japanese 2 strokes and I think you can substitute cr parts
Thumbs Up!

I recall going on an organized trail ride with about 30 riders back in the mid 70's and there was one MT125 in the group. We got to the big hill-climb near the end of the ride and being one of the more experienced riders in the group I went back down to help those having trouble. The MT had only got about 1/4 of the way up so being young and stupid I offered to give it a go so went back to the bottom and got into it but what a hopeless machine. It had zero bottom end like a CR but the topend rush didn't happen so after getting about twice as far as the owner it took 3 of us to get thing to the top with over heating motor/clutch. We almost pushed it back down the hill to be left at the bottom where it belonged.
Not sure but I think the motor cases are the same as CR125 and the barrels will interchange but with smaller ports. Frames probably are similar just with extra brackets for road gear.

The MT's were as mediocre a bike as the CR125M was good.

As a 17 year old I CR125M top ended a registered MT125  including fitting the down pipe.

It didn't work well at all; the 5 speed MT box just couldn't cope with the narrow power spread and the points ignition and heavy flywheel was not up to it.

I suppose with some decent rear shocks and a stock engine you could have some fun at club level Pre 75.


If you love it, lube it.

port the mt barrel so it will work with wide ratio box,i took my ts185a p/port exhaust port up a half mm at a time and got a good result at 1.5mm.anymore and the bottom end power suffers on small capacity motors

My recollections of the MT125 from a long time ago.

Somewhat under powered, good brakes and it handled very well.

Looking at it from now at an older age and less concerned with racing one I think it would make a good vintage trailbike.

Good handling, good brakes and reasonably light. The lack of power probably wouldn't be a problem as you could just hold it open and it's not going to try and kill you or wear you out
The older I get, the faster I was
