Title: 848/1098 front end on monster
Post by: He Man on December 22, 2009, 05:25:31 PM
theres a few combo 848/1098 fornt ends complete with forks, brakes, and masters with clip ons. Was wondering if it is a direct swap on as far as the rotor offset goes...aside from needing the get a new triple that is.

You need 5mm adapters between wheels and rotors

Thanks. That shouldnt be too hard. theres a full front set for $800 bucks for 848 front, and $1500 for 1098 front end i think the 848 will be plenty good.

WAIT....for a deal.  I paid $625 for my 1098 forks, and they already had ohlins 25mm cartridges in them  [thumbsup]  Calipers (1098 monoblocks) are worth around $4-500 used....

 It depends on which Monster you're trying to install them on.

 The S*4 Monsters are not a direct fit but still not too difficult. The axles are both 25mm so no worries there. The Rotor offset on the Monsters are 10mm where as the 1098/848 is 15mm so a spacer is required. Hooligan Machinist just made a set for me and made a few extras as well so there not hard to source right now.

 The other issue is the hub on the wheels. It's wider on the 1098/848 so you'll need a spacer machined for the axle.

 Here's a pic so you can see:

 If the bike you're trying to do this to is a newer Monster without the speedo drive on the front axle then just use the stock spacer on that side. My 996 has the speedo drive so I used that but I had to source a different set of rotor bolts for clearance issues. Once the 5mm rotor spacer is installed the factory rotor bolts will make contact with the speedo drive. I special ordered a set of M8 1.25 x 25 stainless button head bolts that have a lower profile from a local hardware store which should do the trick. We're only talking about 1-2mm difference.

 Here is a few pics of that side of the bike:

 Other than that and the triples it's pretty stright forward. Just keep in mind that if you use the front end from a 1098 then you won't be using the spacers on the calipers. The 1098 uses 330mm rotors where as the 848/Monsters use a 320mm.

 I'm in the middle of doing a 1098 swap on my 996 so I'll post up the entire process with pics once it's complete.

The 1098 forks fit my S4rt monster.. direct....but it has the 5 bolt rotors.  The rotors are the difference to my knowledge, you would need the corsa 6 bolt rotors which have 5mm less (or more) offset....or you can do the spacer thing.  

Spacing radial calipers is easy, and the axle is the same as well.  [thumbsup]

My bike required no spacers anywhere, axle or otherwise.

 Thats because the S4Rt/S4Rs have different wheels. Any of the S2R or regular S4R bikes will need spacers for the rotors and axle.

The wheels on the S2Rs have 6 bolt holes for the rotors, the S4Rt/s and the 848/1098 have 5...

 Correct. Which is why they S2R's will need 5mm spacers for the rotors. The 6 bolt rotors have a 10mm offset with the exception of the 748R/996R/998R bikes which have a 15mm offset. The 5 bolt rotors found on the S4Rs/Rt and the 999/1098/848 have the 15mm offset. I have been considering swapping out my wheels for a set from an 848 in the future as well to eliminate the need for all the spacers but I need to figure out how to keep my speedo drive with those wheels or chage out the gauges.
