My new bike.

[Trousersnake]

I have been wanting to experiment with other bikes and traded my 2006 RMZ-450 for this

2006 Kx250f with a athena 290 big bore, vortex ignition system, stage 3 pro circuit head with oversize titanium valves, stage 2 cams, 39 mm carb, quick shot, r&d fuel screw,full yoshimura system(rs2diamond) with titanium header, c v4 radiator hoses, asv levers, mdk graphics, black powercoat frame and swing arm, twin air filter, sdg step seat, tag clamp with oversized tag bars. mcr suspension.

My question is The guy I got it from said pump gas? Should I chance it?

I havent ridden it yet ( ridding this weekend ) how is this going to stack up against my 450?

The old RMZ

The New Kx250f

depends on riding style if you carry more momentum into the turn I think you will like the way it hadles better but youll notice it still does not pull as much if you suck at a turn b-4 a jump.

[shouldabeen]

big bore kit not high compression kit? pump gas is fine id still run the high octane though.

[Trousersnake]

What type of Power do you think its making? I could tell by loading it in the truck that the weight difference is amazing.

Would it be ok to put a 110/90/19 starcross MS3 or should I stay with a 100/90/19?

[Jonah52]

a 110 shouldnt hurt it at all not much bigger. Tell us how it rides. U should get black rims to complete the package

[Trousersnake]

He had black DNA wheels with Talon Hubs.. And put the stock back on..I think they would of fit the RMZ-450 and he wasnt budging..

Do you think it was a decent trade?

[Trousersnake]

Going to Leota Trail and Geels this weekend.. If anyone in michigan want to do some trail ridding.

[mattehkx]

love the black frame and swingarm! looks great!

[kxtwofiddyeff]

watch bc with the ti4 exhausts 110's rub so i dont think youd want that but with the stock exhaust it wont rub

[ncdirtrider249]

that was a nice zook...the kxf looks great man...ive been thinking about the big bore kit for my bike (07 kx250f) let us know how it is in comparison...i was between an rmz450 and the 250f when i got mine

[Trousersnake]

Well Its probably around the same power as the 450 .. Just cant lug it into the corners like you can a 450.. Love the weight..

That puny 100/90/19 tire has to go..

Are you sure a 110/90/19 wont fit with the yosh exhaust.. I ride alot of sand and feel like I have a mountain bike tire on the back.

I cant believe this Bike has a 4000 dollar Head.. What could pro circurt possibly do to a head to put that type of price tag on it.

[mattehkx]

there would be some special porting or setup that only pro-circuit have found with their R+D. plus you are paying alot of coin for the name.

[kxtwofiddyeff]

both real well kept bikes

[Pr1malR8gw]

Well congrats. I how ever think the bike at those angles looks fat like a husaberg or something..

I like the black frame and polished upper spar but the black swingarm is to much imho.. But Hey glad you like it.

[Trousersnake]

I think that white Frame sticker is what is making it look fat..

I didnt want to go the polished route.. to much up keep..

I Polished my old YZ450F and it was night mare to keep looking good. Plus I was afraid to ride it and would catch my self Trying way to hard to keep it clean

I was going to do the RMZ But I didnt want to worry about it looking like a show peice rather then ride it.

T-Snake,

Looks good- but the front brake line is on the wrong side of the fork. You can re-route it by unbolting the caliper and not breaking the line. I'd move that, so it doesn't get caught on something.

Sweet ride, let us know how it feels compared to the 450...

That is steep, but I know that they have special Beryllium/copper valve seats installed along with better valves and springs. Those valve seats lead away heat much better than the stock ones.

Better, btw, depends on what you want...

Pro Circuits better is more performance, and less engine life.

Stock is what it is, but has a better chance of living a bit longer between overhauls.

I remember MXA writing that Villopoto never got more than 5 hours on the engine before the valves were toast, and that was on his practice bikes!

Well, he might be riding it a bit harder than the average Joe... hehe
