    Who's dual-sporting or riding one? Love it, hate it? Best thing since sliced bread or a CRFX wannabe?

    I'll go first. I love mine.



    It has:

    Tag and title for street-use.

    Rekluse Pro clutch

    3.2 IMS tank

    JD'd

    AIS thrown away

    Stock exhaust (hate noise)

    Cycra's

    Devol Skidplate

    Pro Grip Rally grips

    A mixture of tires from MotoZ to Terraflex




    I have never had any trouble out of this one. It has 1200 miles on it now and I'm not sure about the hours. I change the oil every now and then and ride it. Lots of war stories of bad electric systems were reported, but I've never had to charge mine. E-start lights the fire everytime.

    I'm anxious to hear if anyone else out there DS's one, or just trail-rides one. The new has now wore off enough for this bike to get it's own thread.

    I've definitely considered one of these bikes. They've been written up pretty well and I think could be obtained for *a lot* less than a new Husaberg or KTM.

    All you owners please post your impressions, images, war stories, likes and dislikes.

    I picked up mine in Charlotte NC for $5200 OTD. It was a new '08 leftover. I got it this past April. So far so good.

    I did change out the rear spring though for a stiffer 5.4kg. The stocker is a 5.0 and that's meant for a 135lbs. rider. I'm 190lbs. with gear and now the bike doesn't sit like it has 1'' Kouba lowering link on it. It doesn't bounce off the bumpstop anymore in the rear, either.

    The KLX steers so light. It has a definitive RM/RMZ steering feel to it. That's one of the first things I try to get a bike to do. Turn. My CRF450X was very hesitant to turn no matter how high the forks were pulled up.

    The motor is silky smooth with loads of bottom and mid. Adding the Rekluse Pro was simply cheating. I could never get over 50 miles on the stock tank before hitting the 10-mile reserve, so I went with the IMS 3.2g tank. The only drawback to using the IMS tank is that you have to run a KX450 petcock and KX450 shrouds. No biggie there though.

    The tranny is a wide-ratio 5speed and it does great on the road even with the stock 13/50 gearing. With that gearing you can still cruise at 55mph no problem but 60mph is a little buzzy. I went to 14/47 and now can cruise at 65mph without stressing the engine so much.

    The suspension is so plush and perfect for trail riding or dual-sporting. For pure racing, I'd go a spring stiffer on the front, and leave the 5.4kg on the rear as it's perfect now.

    The brakes are very strong and some say too touchy. I prefer mine that way so no issues there.

    There were a lot of claims of KLX450's being boilers but mine has never boiled. I run the JD Jetting setup which consists of: Red needle on the 4th clip, 165 main, 48 pilot, no o-rings on the accelerator pump and the AIS is removed. I cut off the top of the airbox and left the sides alone as to not let water in.

    The stock exhaust is restrictive but it's whisper quiet so I've left it alone. The KX450 exhaust bolts right on but it's loud as hell. I took it off after one ride.

    Oil changes suffer with the stock header because it has to be moved out of the way to get to the filter. A KX450 header remedies this via a straight pipe instead of the ''tuned for low-end'' stock header. There is a sight glass for the oil, no dipstick. When cold you can't see oil at all. After 3 minutes of warm-up you can see it fine right in the middle.

    I like the KLX450R's engine design a little better than the newest KTM's (non-RFS) and the CRF's. Those engines separate the engine oil from the tranny oil and the seals are prone to go bad....you have to split the bottom to fix that and that just can't be fun.

    I'm anxious to see if it will hold up to the test of time and so far it hasn't let me down. I DS 75% offroad and this bike fit the bill perfectly for my needs.

    Damn those are nice bikes for the money can't beat em. My riding buddy has one it's a blast to ride all low down torque great off road bike. It will be my next bike unless they come out with a 450S with a 6 speed.

    I'm not sure of the exact weight. But I've rode 'em all from KTM's to CRF's and it's the same more or less. It is a light feeling bike because of the light steering effect. If feels lighter than my CRF450X did. I'm sure that's just the ''saddle weight'' though.

    It does feel lighter than a DRZ though.

    I have an 08 that has been dualsported with the baja designs kit. It is street titled in ct. The bike has been a love hate relationship so far but hopefully it is tweaked to perfection now. I will start from the top. I paid in my opinion way short money for it. 4000$ fully dualsported from the beginning with 200 miles. I attribute this to a complete lack of demand for the klx, it seems to have never caught on as a kdx replacement. I needed to have the suspension tuned for my weight, so off it went for stiffer springs all around and a revalve to compensate for the heavier springs. Also went with the bigger 3 gallon tank and did a leo-vince x3 muffler. The jetting on these bikes seems to be way more tricky to get perfect compared to previously owned bikes. The team green jetting from Kawasaki seemed to be spot on except for the pilot witch remaned stock. So far with the modifications I made it is the fastest, best handling woods bike I have ever owned and truly feel it has made me a much better rider. The race results show that fact to be true.

    Tossing out some pics... [​IMG] [​IMG] [​IMG] [​IMG] The dirt tires are DOT legal Pirelli XCMH. Only problem was a leaking counter shaft seal in the first ride. It was a squished o-ring during assembly and fixed under warranty.

    Lol I'm busted! I trade bikes like they're goin' outta style. Had this one since April and now I'm movin' on. I'm going back to a 2stroke for now, so I'll try and keep it around for a season before I move it on too. I'm going for this....

    I think the lack of success of the KLX line exists in the KLX450R. Now first let me say that I have put my money down and phurchased two KLXs in the last 3 years. My neighbor bought a new (left over) KLX450R this last summer, partially because I own KLXs.

    The problem with these machines (KLX450R) is that they will not function properly as delivered. They run lean and hot. On hot days they litterally boil the fuel out of the tank. The battery is small and weak, which normally would not be a problem, but when coupled with a lean bike that stalls when warm you end up trying to kick a reluctant to start machine ... alot. The chain guide pukes in a few rides. I have pushed, kicked, and swore at this new machine more than my last three combined, and it doesn't even belong to me.

    All of these items are fixable. JD makes a jet kit that fixes the lean jetting, a chain guide that doesn't suck is available. The tank can be insulated, and the jetting seems to reduce the boiling. But just like the foolishly restrictive stock pipe on my KLX250s, defects that esentially prevent proper operation stock really hurt the KLX line's image. It is a real shame that two off road rides were esentially wrecked because this thing needed to be "sorted" in ways that Kaw should have handeled.

    I think you'll find this is not a unique situation, when it comes to the 450 enduro class, in general. Search the technical forums for any of the modern four-fiddies, and you'll quickly discover that, thanks mostly to ever-tightening govt regs, that they all come delivered in a corked-up state that requires some after-market tweaking to dial in properly.

    But the good news is, they can all, including the KLX450R, be turned into truly amazing off road bikes for a relatively small cost outlay. About $150 will get you a JD jetting kit, a PMB exhaust insert, and a heavy-duty chain guide to sort out the KLX450R.
