The steering stems are incompatible, though. This is a pain in the butt. You have to press both steering stems out of the triple clamps. This is no small task, as they're both shrink fits with about 8 thousandths of an inch interference. This requires a lot of force to dislodge, and it makes a big bang when the 10-ton press finally pops them apart.

I then substituted the Guzzi steering stem for the GSXR steering stem in teh GSXR front end assembly, and bolted the whole thing on the Guzzi. This required machining a small spacer to fit the smaller Guzzi shaft in the larger GSXR lower triple clamp hole. This was the easiest way to accomplish the conversion.

The Nissin 4-pots are de-linked. The stock Brembo front master cylinder wasn't driving the huge pistons in the Nissins too well, so I'm using a Macgura master cylinder It's originally for a '79 BMW R65. This works pretty well, and provides useable braking.sIf I did this again, i'd try to find a littler larger (~16 mm) master cylinder that bolts right onto the LM IV controls like the Macgura did.

The GSXR front wheel is wider,and probably lighter than the stock Guzzi wheel. It worked very well with this conversion.

Approximate cost (doing all labor myself,and using mostly used parts) was around $1400 for brakes, wheel/rotors,clip ons,master cylinder and miscellaneous parts.

1)'92-94 GSXR 750 is what i used- The only thing that I'd really worry about is that the fork tubes' uncompressed length is the same between the guzzi and GSXR. this maintains close to factory steering geometry.

2) I used the Guzzi steering stem, so the steering head bearings were the same as stock- I replaced the stock ones with Timkens-they cost about $10 each from a local bearing distributor. Much cheaper than through a Guzzi dealer. Again, I machined a spacer so that the Guzzi stem could be pressed into the GSXR bottom triple. I used about an .005" interference fit between the stem and bottom triple clamp.

3)I used GSXR triple clamps, clipons,front wheel, 4 piston Nissin brakes. All from the GSXR model. I used the Lm IV controls. The fork tubes are about ~54mm where clipons attatch. if I were to do it again, i'd get heli bars. Not that much more than GSXR clipons, and more adjustment. The jap clipons are a bit much on long rides, unfortunately for my back... I needed to bore the top triple clamp out a bit to stick the steering stem though it. No big deal.

4) I used a Macgura master cylinder from a R65LS because it bolted into the LM IV controls pretty nicely, and i wan't sure if I could clear the controls with a Jap master cylinder. Since the 850T controls are probably even junkier than the Lm controls, you'd probably be better off going with the Jap master cylinder. Yes, brakes are de-linked, too.

5) I was able to use thte stock steering damper from the LM IV. It's cranked up so that its influence is significant.the handling on the GSXR-equipped LM IV is unmatched! Wider GSXR 120/70 R17 front wheel= *very* smooth steering transitions. if you're going to do the forks, i'd recommend the front wheel as well! I got a bit of a wobble with no steering damper during high speed and extreme maneuvers, but it may have been because of loose steering head bearings.

Keep in mind that I did this mod to a LM iV, which had a longer steering stem than other tonti frame bikes. This shouldn't change much if you're using the stock 850T stem- The head bearings are probably the same as mine- just a longer stem. >

my costs: $200 for front wheel and discs. $450 or so for '92 GSXR 750 forks, triples, and axle. $20 to replace the axle that was bent ( I don't wanna know how...). Try the Rice Paddy here in Columbus, OH as well. Tom and Silka there are familiar with my bike, and helped me with parts. i know that they have wheels and they might have other stuff... Meaasure the uncompressed length of your fork legs- that's the only spec that I'd want to match between the Guz and jap forks. You can always move the forks up in the triples if they're an inch too long, too. Call Erico Motorsports - they might have a front end laying around. They can tell you what they go for anyways. II've seen GSXR stuff on ebay as well. Just be careful that what you're buying hasn't been wrecked, as is the case with some Jap sport bikes...

Also, be prepared to have to make wheel spacers on the lathe. If i was doing this again, i'd make sure that my front wheel was nice and wide, but i don't care about looks too much( front wheel=black, rear wheel =red, oh well...)
