Tire Suggestions for CMF 125 XC Bike

[tonupchad]

Hello all,

I need some new rubber for my 125 CMF Cross Country bike.  I've reviewed all the previous threads on the topic and see that folks really like the Pirelli MT16's but when I went shipping for them I quickly became confused on sizes and variations.

Please help!

I have to get something ordered today for next week's race.

Thanks,

Chad

MT16s are too big for a 125 on the back tire. The best option right now for a rear tire on a vintage 100/125 is the Duro HF335 in 4.10-18 size. I run that on the back of my 100 and an MT16 on the front.

What size MT16 do you run on the front?

Thanks!

Too many people use a tire on the rear of these 100 / 125's. I have seen 125's with a 4.00 x 18 (old size) and that is too big of rubber for the 125's. I don't know what the conversion is for the "new" sizes, but nothing bigger than an old size 3.50 on a 125 is best. Bigger and you use too much power just to turn the tire.

There is only one size of front MT16, 80/100-21, basically a 300-21.

Donny, you are exactly right I see vintage 125s all the time, even Elsinores, with modern 100/100-18 rear tires which are WAAAAY too big. The reason I use, and recommend, the Duro HF335 is they are a little under size for the claimed size. The 4.10-18 is almost the same size as the old school 3.50-18 and its perfect for a Sachs 100/125.

Brian is dead on !

I have to give Dwight credit, he recommended the Duro to me as a replacement for the Cheng Shin. Since Cheng Shin went out of business, I think the Duro 4.10-18 is the only new tire that will fit on a Steel Tanker.

Cheng Shin actually didnt go out of business, they renamed themselves CST and dropped all their old tire designs like the C755 Metzler copy and the C183 Barum copy which were the only ones that fit the back of small bikes.

Has anyone tried one of the Kings Tires? I see on their website that they make front and rear Metzler copies. They have a 4.10 x 18 rear, and suggest it to be used on a 2.50" width rim.

Reasonably priced, $80 for a set.

I cant give a personal review on that particular tire, but I bought a '96 KX250 a few years ago with another model Kings tire and it was the worst tire I've ever used.

Brian,What made the Kings tire you used so bad?No traction,wore out quickly,or what?I've not used one,but am needing some 100/125 tires soon too,and the pickings sure seem slim.Thanks,

p.s.-i like your new race transporter(saw it on face book).That's about the size trailer/toy hauler i'm thinking about-nice.

[brian kirby]

It looked good, and it wore like iron, but it had no traction at all. A different model of Kings tire might work better, or it might work better on a small displacement bike, I cant really say.

I don't know where they came from but your dealer can order the C755 4.10X18 (and the Duro HF355) from Parts Unlimited. They have them in stock right now.

Hi, Does anyone know where you can get the King tires mentioned above? I went to there website and they show tires and prices but dont say where to get them.
