better brakes for a 620

[DarkMonster620]

with those rotors and pads? you should be doing endos . . .be carefull

Thanks for your help everyone.

I've sourced a caliper and master cylinder setup off a S4 and have ordered a set of braketech rotors off ca cycleworks.

Should be a big improvement over the stock brakes!

Excellent setup.  What pad are you going with?

I'm in the same boat. Decided my 2005 620 brakes arent cutting it when a car going the other way made a left turn in front of me in the middle of the street (not at the intersection) saw me then panicked and braked (essentially blocking the road) while I was doing about 30mph. I had about 3 car lengths to stop and braked (front and back brakes more front as there was a little "endo" going on. I didnt want to slam the brakes and lose control or lock up but I was not able to completely stop and ended up slowing to about 10mph before hitting the passenger side of the vehicle. I flew over the handle bars into the passenger window. I was geared up (helmet, padded jacket, gloves, boots) so I was not hurt at all, my bike was not damaged in any way so I was happy about that. Cops came and gave the driver a ticket for not yielding right of way. (Thats police talk for being a dumbass ) Anyway I'm wondering if better brakes on my 2005 620 would've made a difference. I replaced the rotors and pads last year myself. I'm due for my 12,000 mile service in about 600 miles so I'm pretty sure I'll get a brake fluid flush. Not sure if that will help. I'm also nervous about upgrading the brakes and having brakes that are beyond my control and stop too hard. Obviously there would be an adjustment period. Any thoughts would be appreciated.

Duck Off . . . will assume you have the small diameter rotors and 2 pot calipers . . .I started out replacing the pads for HH sintered from EBC and DOT4 brake fluid . .  big improvement . .  after that, M1000 masters, even better, then 4 pot calipers and 320mm rotors . . . had to go back to coffin master for a while, now, RCS brake master ...... endo time big time .. . had to practice in a parking lot with different settings between 18~20mm adjustability . ..  go for 848/1098/1198 masters or SF masters . . first and get used to them first . .

I put 4 pot brembo calipers and 320mm rotors on mine, with a 16mm coffin master.

It really transformed the brakes. Huge improve.

Don't worry about grabbing too much brake, the 4 pots are really controllable and progressive. More so than the little 2 pots.

See if you can find an older 620 to pull parts from. My 2004 620 came stock with gold 4 pot calipers (same as my 748) and a metal tank.

If I can source some used Brembo 4-piston calipers  (found some Gold Calipers off an M750 2002) can I use my existing brake lines, rotors and Master/Slave Cylinders and essentially just replace the calipers?

yes, if, the rotors are 320mm

For those of you guys with the upgraded brakes would you say it is more beneficial to:

-change to 4 pot calipers with rotors
or
-change the master cylinder, more aggressive brake pads



for those with the 4 pot calipers are those 2 pad or 4 pad? If i'm not mistaken you theres 4pot 2 pad calipers and 4 pot 2 pad calipers.

found this on the forum. Very informative...

4 pot requires 320mm. rotors, not the 300s the bike came with.  Yep, 4 pot will have better bite and be less flexible than the factory floater.

What bikes are suitable donors for 320mm rotors that will work on the 620?

[DarkMonster620]

you can get the calipers and rotors of an 998, any Monster with 65mm caliper mounting, SS bikes,  . ..

My calipers came of a 998 and the first rotors too . . . MY01

Don't forget about front suspension upgrades with improved braking. After just a pad swap on my '04 620, Gold line 4 piston, I got alot of pulsation from the front end when stopping.  Putting a zip tie on the forks, I found I was bottoming the forks even under light braking.  I have sence installed a set of 998 forks with .85 springs.  No more pulsation & I am able to apply more braking pressure. I have a set of Diavel radial master cylinders I need to get around to installing as well.  I expect the monster to have similar braking performance to my 848 after that.

I hear you 100% on this.

I have some 320mm Brembo snowflake rotors on the way.  Here's hoping that they fit!
