2006 KTM 250 Sx-F – Dirt Rider

I now officially consider myself a KTM No, my name wasn’t on the title, but I put saddle time, elbow and 91-octane into our 2006 250 to justify ownership all the same. In our the 2006 MXers” article in the May ’06 I said I wanted to run the KTM all year for a of reasons.

One was due to the fact that I had really ridden the orange and I felt I should for both the KTM readership we have and out of sheer for this particular bike. The reason was to observe the durability of a I knew nothing about. I into this test a clean slate and came with a great impression.This wasn’t just a motocross bike.

True, most of the 50 hours I throughout the past year been from buzzing local tracks on practice and numerous minor races. But bike also went six straight through a grueling, endurance race and did its fair of 45-minute grand prix-style Basically, I didn’t baby it.

I it like you or your kid would, no special attention to internal save for oil changes every to eight hours, a valve at 32 hours (which showed no movement of the valve train) and a top end rebuild near the end of the testing (45 hours).When we tore into the at KTM’s shop for this and year-end rebuild, we discovered a lot of First, prior to cracking a bolt, we did a standard leak-down

For those who don’t know, a test determines the condition an engine by pumping it full of air and how much leaks out. The worn out the engine is, the more air out. It’s simple. this KTM 250 four-banger showed readings of less than 4 leak-down.

We kept trying, but the internals were certifiably and refused to leak down than that. At that KTM’s top in-house technicians the need for a top end rebuild. We did one anyway none of us, including the head of press department, had ever into one of these motors.

wasn’t out of laziness on their they’d just never to do it! Before we tore off the cylinder we rechecked the valves. They still well within even after enduring than 13 hours since we looked. Then we pulled apart to inspect for wear and

The piston coating was barely away; under the micrometer it was one-sixth of a 1000th off of stock. The were in decent shape but a little sharp on the edges, and was essentially the extent of engine So we replaced the rings, buttoned up the and called it good.The only business we had was upon reassembly.

the bike ran perfectly, it, for no reason, overheating and spitting coolant. We the worst, a blown head or something allowing pressure the cooling system from our We checked all this and were to find that the problem was the air was never bled out of the head and not allowing proper cooling. was easy to fix by just using the bolts and adding some

Then our problem was cured.Wrap maintenance-cost-calculating brain around for a minute. We essentially owned and a bike for a year, and our only expense was oil, fuel, and some suspension servicing-operating really. I’d say we got an immense value.

we were hanging around the shop with nothing to the race team guys coming by and asking what we were using. “Stock,” I reply. Then they’d ask how the held up. “It’s stock,” I’d “plates and everything.” Sure, I have replaced the clutch a few hours before I turned the in to freshen up the initial bite of but was it necessary? Not even close.

This is good and bad. a big barrel of fun once you get the hang of it, and chasing down those 450s is easily handled. But if jumping straight off a Japanese you’ll be wondering what the KTM so long to get it pulling. We found the fix was gearing, but nothing else a serious dent in the bottom-end of course, there’s the suspension

The KTM suspenders take about two to get used to when coming off a bike. Then they very well. The misconception of suspension performance is just

And a couple of hours in the suspension to add the personal touch that riders prefer can make it a system.In conclusion, I have to I fell in love with orange bike. It could be it’s just different-or it have something to do with it letting me down.Running Tally
