This is BRP's chain guide for the KDX, I was impressed with the quality. It is almost a half inch thick on the inner and outer sides, it is wide enough for an O-Ring chain also. The overall width is about 1 3/4's of an inch. Put's the stock one to shame!!!

how much munny?

ah like $70

Replacement blocks available? It's a mono-block, ain't it? So...no replacement blocks possible...so when it's worn out you gotta buy a new one?

So...that's completely bogus?

'zat so?

Ya know, a person could probably go to the local plastic supplier and buy some HDPE sheet (or whatever it is) and make one of those. That stuff cuts with wood working tools nicely.

If anyone ever has an old one they are about to throw away I will take it and make machine drawings and then post them here.

The one above looks like it is made out of four pieces; two pieces for the side plates and two pieces between the plates to control the up and down movement of the chain.

I have tons of that plastic.....

But..but..but...

The top pic looks seamless to me on the bottom..and that's where it wears. I see only two pieces.

I have some HDPE blocks (or whatever it is) I've cut replacement blocks out of for my OEM guide a few times. It's even green!!

I take out the old block (held in by screws at the bottom..no such screws at the bottom of the one pictured), trace the shape onto a hunk of the green stuff, cut it out with a scroll/jig, use a wood rasp to smooth it, drill it, and my guide is as good as new.

I went looking for a cutting board made out of the stuff (the thickness I was after..for a different application) just the other day. One cutting board: $25!! And that was at a discount membership store.

I passed.

From here!

No its not one piece , you can't see the seems in the picture.

NO wait, I am wrong it is only two PIECES!!!! yea actually I have never thought about replacement blocks good point. Although I have had the stock on the bike for 7 years and never had to replace those so Im thinking this will last a while.

I'm sure wear on the bottom block depends on a lot of stuff..how much mud you cram into it, chain slack...

I've replaced mine 3-4 times..so I know they wear out. The first time I replaced the block, the chain had eaten through to the screws. Obviously that block needed to be replaced some time before then, 'eh?

Hmmmm, never even looked at mine....

Mr. Wibbens, check it.... maybe you start to use the two bolts because there's no rubber over!

I change mine at 2000km with a 47 rear sprockets and maybe at 1500km with a 48. I ride in mud often too...

Yes, it depends of the mud, the size sprockets and the chain slack.

I love my Fredette because he's wider for O-Ring chain.

What is this km stuff.... 2000km is like 800 miles or so.... right?

No not quite.

KM times 5/8 = miles

It's called the metric system, you know like what they use during the Olympics and every where else but the states.

Well... if you know miles.... use that!

The odomeder on my KDX was in MIles...

I member back in grade school, they use to teach us about the "metric system" and how we needed to prepare for it 'cuz it was coming....

Wonder when it'll get HERE?

It hoestely makes a shitload more sense.

Ask 20 random people if they know how many feet are in a mile, and I'd be suprised if 3 of them got it right.

A tips for you, KDX lovers!

NEVER BUY a Kawasaki chainguide rubber.... the price is so expensive!!!

A Fredette or Moose will fit very well and is 10$ and not 24$!!!

Take off hoser, because Canada used to use standard measurement. I know because I remember Bob and Doug McKenzie having trouble switching over to the metric system. They had a hard time trying to figure out how many metric beers in a six pack.

Bob: I think it's like a six, a six pack equals 12 beers and 30 beers is like 42 beers, 42 metric beers.

Doug: That's good for me, eh. Count me in on metric.

Doug: Yeah, if I drank a beer every mile. So here's a case of empties, I'd say we're twenty-four miles from civilization.

Bob: No way, half of those are mine.

Doug: Okay. Twelve miles.

Bob: We should go metric. Then we could drink a beer every kilometre, not every mile.

Doug: So?

Bob: So... kilometres are shorter than miles!

Doug: AH! So we drink more beers.

Bob: Exactly. What's the conversion factor to go from miles to kilos?

Doug: Uh. Double it, and add thirty.

Bob: No, get out! That's temperature.

Doug: So, it's still metric.

Bob: Okay. So how many beers could we have had, professor Doug, assuming we drank twelve each?

Doug: Um. Hey! Are you implying one of us, possibly me, drank more than twelve?

Bob: Wha? No, I'm just sayin' it makes the math easier...

Doug: So uh, twelve beers, that's... um.

Bob: Twelve kilometres.

Doug: Right. Uh. Twenty-four. Wow. And uh... thirty is... uh... holy smokes!

Both: Fifty-four beers!

Bob: Wow. I'm switchin' to metric.

Doug: Beauty, eh?
