Monoblocs on GRiSO and more

I have been kicking around getting the radial brake and clutch set up. Then thinking is I do that, do I get monoblocs?

Then thinking if I do that, do I look for some fork lets off a RSV and get a really sweet front end set up.

Then started thinking I was insane. But, what would I need for a front end swap with monoblocs, radial MC and some Ohlins off an RSV?

I went radial then monoblocs. Betwixt them I installed Matris cartridges. Cost would be on par with buying RSV4 front probably. Don't forget the Ohlins won't work with the GRiSO triple clamps. I suspect you'd need a complete front end and would have to match head bearings.

I tell you, a radial M/C and monoblocs create some serious stopping power.

Since I'm a Guzzi owner hereby making me a cheap bastard, what radial brake and clutch pumps can be bought off a crashed out bike?

Birch, any modern Ducati.
I find Sun Coast Cycle Sports in Florida a good supplier of not only wrecked parts but they buy complete and road worthy 2nd hand bikes and strip them.

Also the best bang for buck with calipers for your stock 1100 front end are the Brembo's off a 998R as your bike runs Goldline axial calipers. These are a direct bolt on 4 spot, but they have 4 individual pads per caliper (1 per piston) and have massive initial bite. With a radial master I can brake with a solitary arthritic finger, still hurts [You must be registered and logged in to see this image.]so I use two fingers and it stops bloody hard. Just check distance between mounting holes.

I had this set up on my Bellagio forks, swapped front end for 2004 Multistrada 1000DS but these accepted my 998R calipers.

For me the front end swap of forks, triples and axle required a new steering stem and wheel spacers at $500. Then fabricating a steering stop, headlight/instrument mount and ignition/lock mount.

Not a job for a cheap skate.

Well I picked up a set of M4-100 monoblocs off a wrecked S4Rs for a steal of $270.

Now to find the pumps/levers. Interestingly, they are kinda pricey even used. Thinking for the extra $30-$40 just to get new ones.

Should I replace the stock lines while I am at it?

Yes. The stock fitting angle is a pain with the radial m/c's and also the M4's. Plus, I suspect the lines will be too short. Mine were.

Looking at a radial pump/lever/resivoir off an 1198 S Corse. Seems to be the same dealio. Need to confirm it's the 19RCS

Also, can you run the monoblocks with the stock GRiSO coffin MC?

Yep!

Hey Birch, you still riding an 1100 GRiSO?
Am I mistaken but don't they run axial calipers, not radials?

I am on an 1100.

And I'm daft enough to say I don't know the difference.

You're correct, Wayne. Some sort of adapter would be required. Or new forks.


The M4's won't bolt on to the axial brackets of the 1100.

Axial versus radial when referring to calipers means the angle at which the bolts that hold the calipers on are in relation to the disc. For m/c's, it's the direction of the piston when compared to the bars.

Oh fk me.

So the stuff I was reading was for only the G12?

Yep.

Doesn't stop you from using a radial m/c.

Cock.

Anyone then know the specs on an Aprilia Tuono forks and how I might get those fixed up for my GRiSO?

I have a supurb custom shop by me, Analog Cycles, and Tony is a good man. Just need the specs.

Knowing Piaggio, they'll probably bolt straight on. Sorry. Don't know the Tuono specs.


.

Not quite a straight slip in.

Birch, if you want to keep geometry same as stock.
1. Measure length of forks (fully extended) from centre of axle to top of fork tube.
2. Measure triple clamp offset. Centre of steering stem directly forward, to imaginary line drawn between the centre of each fork.
3. If geometry changes (ie rake and trail) then you need to understand if it will be better or worse.
4. Check to see if both bikes use same steering bearing sizes, or if the Tuono ID and Guzzi OD can be found in a standard bearing chart.
5. Manufacture of steering stop and attachment of ignition/lock plus headlight/instruments.

If that is all too much, go back to my post on the Ducati 998'R' calipers.

Even after several pints, I do recall you saying that.

Then I saw Mark mounting the M4's. Didn't know there was a different configuration.

Seeing I already have the monoblocs, access to a top level custom shop, why not do something special with some Tuono Ohlins??

Ya know, until Pete talks me out of it.

Well double Cock.

Found some 998r brakes and they are $50 more than what I paid for the M4's.

Get some custom brackets machined up. Or is my arse talking?

Might be.

Funny how you learn more about a project and what you are doing after you cock it up.
