New Big Tank Decals & CBR Weels

SteveS · May 29, 2008

Finally got the CBR wheels machined, installed, and running. Added some color to the big BOSS tank as well. I am pretty pleased. I think it all turned out ok.

Man that rear tire just fits in there. There is a bit of a trick to get it in!

The decals are Avery industrial laser printed labels at about $1 per page. They are scratch, water, and solvent resistant. We will see how long they last? Each side is 6 separate 8.5"x11" pages cut together. You can see the seems when you get up close, but otherwise looks ok.

What do you think?

Once I get some riding in, I will post the specifics on how the wheels and spacers were machined.

That looks freakin awesome Steve!!!

Lets have a ride report. How much time does it take to change over to the other set?
The decals on the rims are a nice touch.

Thanks K!

Put about 200kms on them so far. No problems yet. The smaller front wheel changed the fork angle somewhat, so she tends to turn in much quicker. Tires seem pretty sticky. Changed gearing from a 15/48 to a 16/43. Much nicer on the highway. Very smooooooooth. Hoping to be much more comfortable with the turns after the road racing school this weekend. Can't wait!

The front is quick to change - just pull the axle, drop the dirt wheel, install two spacers, install cbr wheel, and matching axle. The CBR rotor was 275mm dia, only 15mm bigger than the stock berg rotor. It was looking like it was going to be difficult to build a relocation plate for the caliper. Only need to move the rotor out 7.5mm! Barely the width of the bolt head. Instead I reduced the diameter of CBR rotor to match the stock berg rotor. There was still enough surface to accommodate the brake pads. The rear is a little slower to change, only because I am swapping chain and front sprocket as well.

Well lets hope that the weather holds good for your first time on a track.
You'll be surprised how much traction you can get out of a nice set of tires on a track.
Especially with no cars coming the other direction.

Let us know how you make out.

I am off tomorrow. Hoping to get out for another rip tomorrow as well.

That looks freaking awesome! but the chain looks a little tight, maybe not...

Steve,

I'm dying to get the low-down on the CBR wheel conversion. They look fantastic and I bet they are cheaper than KTM/Husaberg wheels.

Nicely done.

Cost me about $225 for the wheels including shipping (eBay), $35 for front axle, $10 for spacers, $15 for fresh bearings, and $7.50 for sprocket bolts. So all in for under $300 plus rubber, chain, sprockets, and a fair bit of time figuring and machining.

I always think the chain looks tight too, but I can press it up to the bottom of the swingarm as per manual? Do folks run it looser?

that does look rather nice.
the chain does look a bit tight in the photo but as long as it can just touch the underside of the swing arm immediatly behind the chain slider when the bike is on a centre stand ( back wheel off the ground) it should be alright.

Just finished the local Kawi high performance riding school. What a blast!

Lil berg in a sea of sport bikes. A little intimidating at first

First time out riding on a track. I wasn't "backing it in", but I was a little surprised to see a hot, sticky, peeling, scuffed to the edge, tire! Particularly on a bike I was riding. SO I had to take a pic.

What a blast! Highly recommend it to anyone who spends any time on the road!

The wheels worked well. Only a small scuff on the muffler. I didn't think the suspension was working that hard.
