Honda CRF450R -04 for ice.

Recommended Posts

I drove last winter My 250 on ice with standart suspension and now I want more from my bike.

I bought a old "bigblock" 450 for driving only on ice.

The goal is to make the bike as good as it can be as a reasonable amount of money.

At the moment if have removed from the frame everything what needs to be rebuilt or serviced.

Bike needs:

Suspension lowering and re-shimming for icetrack.

New rims and tyres for ice and highspeed driving.

Engine rebuilt for full throttle driving, crank,valves, piston etc...

Here is some info:http://www.iceroadracing.com/en/index.php?sivu=technology

Here is some video what this thing is all about:

This video gives you some feeling of the speed on fully loaded bikes and grip of the tires on ice: http://www.youtube.com/watch?v=wq-MfYtlZNc&feature=related

Youtube is full of related videos about iceroadracing if your interested about the sport.

I´ll post more to this tread as the project continues.

Today I torned the engine open.

Piston was looking that it was ready to be changed, one gear had a missing tooth, no other signs of damage or eccessive wear.

The plan is to install new crank, piston and valves to engine.

Here is some pictures, sorry about the bad quality, My Nokia covered with oil...

Some update:


The frame has been cleaned from dirt.


Forks have been serviced and lowered 55mm.

The forksprings are now rated for 4.1k and the shimstack is same as a 250R stock stack in on -04.



Front and rear rims are new Exel black with new spokes, wheel bearings and seals are also new.

Next step is to change the steering bearing and service/lower the rear shock.

Okay, the bike is ready to ride.

There is some pictures:





Next step is to go riding and adjust the suspension.

Carb jetting is also one thing that needs to see how it runs, idle is 50 and main 175

I have only one problem at the moment, there is no ice on Finland at the moment, winter is a little late...:bonk:

      Garrett Poucher and Skyler Howes of Garrett Offroad Racing are headed to Dakar!  These US privateers are headed there for their first times but Skyler is fresh off a victory at last week's Baja Rally, won the Sonora Rally in March and this team placed third in the Baja 1000.

      They have a fundraising link set up and could use your help.
      I raced with Garrett at Baja Rally last year and then both of them at Sonora and was honored to pit with them as well.  They're both super guys and work their assess off.  I think they both have good chances of not only finishing the 11 days of Dakar but placing well.
      They're doing some rally training events this Sat, Oct 20 in Santa Clarita, CA and then another Oct 28th in St. George Utah so if you've ever considered learning rally raid navigation, this is your chance!  It's a lot of fun too.  More info on that at the link.
