Grass Hopper is back, with even more stopping power!

While I am deciding on what new Motard tires to buy, I chucked a set of trail rubbers onto my old rims re fitted my dirt option.
I decided to try out this option and to use the much bigger SF front brake rotor. ( Mainly cos I was too lazy to change the calliper bracket, and it's easier to whip on a rotor. ) Well I can happily report that the combination of braided hoses and a large rotor will comfortably put you over the bars and onto your head, if you so desire, without any of the old mushiness the KLX front brake was known for! |
Pretty neat, isn't it! I have the KLX650C which runs the 300mm rotor and it has some serious brake power. I was at the AMA Museum yesterday and noticed one of Ricky Carmichael's bikes that was on display - the front rotor on it was somewhere between a 300 to 320mm. I've never noticed that on any other motocrossers. Obviously Carmichael wanted a LOT of brake power.
I'd love to have the big rotor on my 250 too. I have a 300mm from another 650 wheel and will have to look at what it takes to move the caliper... whoo hooo! more brakes! |

A calliper bracket available from Kawasaki for the KLX 250 SF will move the s calliper to fit an SF rotor. All very cheap and easy if you either live in Thailand, have a friend in Thailand or own a Kawasaki dealership in the USA.
I appreciate the tip. Just looked up the SF rotor size - 300mm! Can do! In the image below is it P/N 43044? https://www.kawasakiepc.com/SSIConve...92534_6214.png |
Yip, that's all you need, 43044, plus the Rotor, which you have. It is a very easy mod.
|
Only problem is that the bracket is ~$115 + the rotor. You can buy an EBC supermoto 320 mm kit for $190. I suppose if you ran across some used parts off of a SF then it might be a better deal.
|
It's a flat steel plate and is similar to the one on the S model, but extended to work with the 300mm rotor. One can be laid out in CAD to suit the 300mm rotor, then cut. I didn't realize it was that simple.
|
If I remember correctly, the bracket has some funky offset stamping where the pad tangs engage so I don't think that it's a simple plate...but I could be wrong.
Mark, if it's a simple job I would be interested in doing this mod if you could provide the bracket. |
