Ice Studs for bikes - a guy called Peter Lundqvist in Sweden fixes us half inch long sharp spikes , they are half the length of proper ice racing spikes.

This is what is typically used over here: traction is no problem with big-bore dirt bikes although I don't know how they would work with 150 HP superbikes!

The problem seems to be more with the front tyre spikes falling out, if the spike nuts loosen (best to loctite them) and use an asbestos board in front of the radiator in case the flying spikes puncture it

Seldom Seen Slim,

it looks smaller than it was. We plowed 6 meters wide, app. 18 feet for this run, but I would not recommend that for public racedays...

About the wheels and studs, i made a lot of different solutions, patterns and studs including tubeless studtires. There is a big diffeence between a wheel you like to stunt with or have fun in playing around in ice an snow and a wheel you like to go really fast with.

Over all i think icespeedrecoordracing is an interesting alternative to go on a save way to very high speeds.

30 years ago we were using 2 cm (3/4") screws into Carlisle grass racing tires.  They offered enough traction to pull knobs off but they were not rigid and would move around a lot.  I think screws work like a negative-rake cutting tool i.e. they grab the ice with a 90-degree angled edge.  "Traction" screws would be oriented in a different direction than "cornering" screws or "braking" screws.  You can hear them scraping when cornering and braking.  By using smaller diameter "street" tires inside the Carlisle (with the bead removed) to put the screw into, longer screws would maintain their angle with less distortion, plus they would no longer pull knobs off.  I think people use motocross tires today with the screws.  Cornering angles could be extreme and it was not unusual to move the shift lever "up" so the bike would not accidentally upshift during cornering.

I'm sure you guys know what you're doing!  I'm just offering this from an old club racer's perspective.  It's been 20 years since I've done this so I'm now out of date.   sad

the pulse jets look good-we made one as teenagers,but almost torched the old mans garage-so we left that one alone.

My friend Jobergg from Sweden, posted these studded tire pictures from their ice lake racing, on another forum.







These tires are factory made but some people make their own.
Gasfot talked about buying these tires for the winter, I belive they are homemade but Gasfot maybe know how it is?

Hi guys !

 My name is Kristian, 39yrs of age, & about to also try this Flying Kilometre for the first time:

Im registered for the event with three vehicles.

 1: My porposly built driftcar, an RWD Mitsubishi EVO 2, running an VEMS fuelinjectionsystem,
     a Precision680 Turbo & using Ethanol as fuel, the engine gives about 550bhp & weighting
     in at only 905kgs.
     Stock topspeed with 15" 195/55 wheels is 240kmh, im running 145/80-15 iseracingtires &
     1500rpm higher revlimiter which "should" enable me to reach 300kmh on tarmac, on ice, well,
     we just have to see. Im attenting though to be fastest 2L turbocar.

2: "Homemade" gokart, using an 125cc shiftercartchassies with an ex: Chesterfield 250cc moto-X
   engine with close to 55bhp., geared for 262 kmh with cartslicks, but icetires gives a lot
   higher gearing so will try & gear the cart for around 220-240kmh,  Using an supercart frontspolier
   & rear wing of an racecar to keep the cart stable during runs. rear wing is totally adjustable aswell.

Kristian, there's hope for you.  If nothing else -- the paint on the bike is great.  As for drifting on the ice, and a kart set for high speed ice maneuvers -- yup, you definitely belong in this group.  Welcome to the Forum
