Hey gang,
As many of you know I am in the process of doing a fork and brake upgrade on my 996. The plan was to use a set of 1098 forks and monoblock calipers while keeping my OEM Marchesini front wheel so I could keep the speedo drive and eliminate the need for new gauges.
Here are a few pictures of the new 1098 forks and the 1098 monoblock calipers.
I wasn't sure exactly what it would take to make it happen but my friend recently bought an 09 848 so I decided to try it first on his bike to see what I was getting myself into. I guess that'll teach my friend to leave is bike at my house for the winter.
Here is a picture of my front wheel installed on his 848.
While fitting my wheel to the 848 I took a bunch of measurements to figure out what was needed for spacers, hardware etc.
The first thing I realized was that the hub on the 848 is a little different. While I could use the speedo drive as a spacer on the left side, I would need to machine a spacer for the right side. Here is a picture of the gap on the right side that I had to make a spacer for.
Here is a picture with the spacer installed. I still need to put a few finishing touches one it so it looks a little cleaner but you get the idea.
The speedo drive required a little work to make it fit and function properly. First, the stock rotor bolts wouldn't work. I needed something with a lower profile so they wouldn't hit the speedo drive. I sourced some stainless steel M8-1.25 x 20mm buttonhead bolts to use on the rotors to help me get the clearance I needed. Unfortunately the lower profile of the button heads weren't enough so I had to machine about 1mm of the plastic off the inside of the speedo drive. Here is a few pictures of the speedo drive installed. I had to special order the stainless buttonheads so I used 3 regular steel until they come in.
Next up were the brake calipers. The 1098 uses a rotor with a 15mm offset and a 5 bolt pattern so they wouldn't fit on my Marchesini wheel. The stock rotors on my wheel have a 10mm offset and a 6 bolt pattern. That left me with two options. I could try and find a set of rotors from a 998R/996R/748R that had the 15mm offset and the 6 bolt pattern or I could have some 5mm spacers made so I could use the Braketech rotors I just bought a few months ago.
A quick post on the DMF produced an offer from Hooligan machinist to make the spacers for me. So a huge "thank you" goes out to Howard!
Here is a picture of one of the spacers.
With the sapcers installed the rotors fit perfectly in the center of the caliper.
And thats about it. I received the spacers in the mail yesterday so I spend last night installing the new forks. I'm still waiting for the banjo bolts for the brake lines but other than that it's just about done.
Let me know what you guys think.
