Hi! Looking for winter tires for my k75
I live in Stockholm, Sweden and need tires for degrees around minus 10-20 degrees Celsius. So wound nee tires with the right softens for the cold climate and preferably studded. Someone got any idea?
-
Shinko Tour Masters and 712's have been fine in the cold. I've commuted at 75-80 mph down to 14F just fine. I wasn't pushing the bike hard in corners but no issues. This was on dry pavement though...no snow

If you have the time to do it, you can get trials tires and put hex head sheet metal screws in them, one in each block on the tire. I have seen amateur ice racing bikes do wheelies on ice with tires set up this way.
My only question is how durable this approach would be. Would the screws tear the blocks or work themselves out? Racers don't do that many miles compared to a street bike used for commuting.
-
the problem is more that i want tires that still are soft in minus degrees, like MS-tires on a car. Trials with hex will become very slippery when i come in to the center of town where there is only bare with patches of ice :/
Would need MS-motorcykle tires with some scarce studs..

You would need to install tire studs yourself on tires with block tread like Heidenau Scouts. Read everything on this page from Aerostich (http://www.aerostich.com/self-tapping-carbide-tire-studs.html).

Good info :) but still need to find ms-tires (soft tires),,

All you need to do is type Mud and Snow Motorcycle Tires in a Google Search. They're not going to be "soft" but they are likely to be made of rubber compounds that provide an acceptable degree of adhesion on dry roads. If you want them to be soft, run them without air. :giggles

Haha :)

You might be chasing windmills. MC tires with soft compounds are usually found in racing or high performance tires which would be terrible in winter. Enduro type might be your best bet but they're not optimized for cold weather. Not much of a market for winter tires for street bikes.

Nice :)
It's stupid that they don't do the wintertires for street. If you want to go off road in winterclimate its just to take the snow-scooter, I've got one, but can't take a snowscooter into town :-/

This probably isn't what you want to hear.
In my misspent younger days I did a lot of winter riding both on and off road. It was a mix of trail riding and racing where I competed in and won winter enduros in New York, New England and Canada in temperatures down to -10F/-25C. Altogether, I would say I've done around 5,000 miles in winter conditions like the original poster wants to ride in. In those days I used Bridgestone full knobbies on Honda 125's and an Ossa 250.
The Bridgestones were our all year tires and the compound was soft and the tread was aggressive enough to give a good balance of traction in snow up to a foot deep as well as on dry roads at speeds up to about 60 mph/100 kph. Our decision to use them was based on the fact that they worked the best in the soft gooey clay we raced in in the warmer months. For what it's worth, we used our old worn out tires because the sharpness of the knob edges didn't seem to be as important in snow as it was in mud. I can't remember what we used for tire pressure, but it was a bit lower than what we ran in the other seasons, probably somewhere around 20psi/1.3bar.
As far as engines, the low output and power curve of the Honda was ideal in helping to prevent the rear wheel from breaking free on acceleration. The Ossa with it's huge low end torque was nice in deep snow, but on the pavement you had to be extremely careful with the throttle to prevent breaking the rear end loose. Breaking the rear end loose on packed snow or black ice meant you were going down, no ifs, ands, or buts, you were going down.
From my experience with my K75RT, I would say that there is no tire available that would work in the slightest amount of surface frost. The RT with that huge, heavy fairing is horribly top heavy and the steering geometry of the front end does not have enough trail to make the steering stable enough. Bottom line, in winter conditions with frozen surfaces an RT is an accident waiting to happen and it won't have to wait too long.
My advice is to put the RT up for the winter and get a lightweight bike in the 175cc range and concentrate on windproof clothing to avoid the effects of wind chill.

+1..... If the Mighty Gryphon states, it is so! Forget riding a K in ice & snow.

ahh, finally, my infinite wisdom in buying a Ural for winter riding is confirmed :riding:
-
Exactly! Three wheels is the only way to go in the ice and snow.

I watched the whole video to see the ordering instructions at the end. (Also to find out how many box tops I need to save.) Damn! I want one!
-
Yea, that was my initial idea, but i already have 2 bikes and a small budget :-/, will have to wait for next winter :-(

Arvid, as previously mentioned, Heidenau makes the Scout wich comes in M+S types, too. Not in exactly the right sizes but close enough to work on a K-bike.
I know of some guys who have used them and they were pretty happy with how they did in winter conditions.
The studs will be up to you, but living where you do you probably have more experience with that. I never used studs, as they are illegal in Holland.
I'd say look arround on this site here and find out what they've got for you.
I'd say a K60 silica (under winter tyres) up front and a K60 Scout M+S at the back (under dual sport, go figure... ) would do pretty good...
