Hello, I've been away a while but decided to get my 2013 KTM 250 SX custom tuned by Derek Harris of Harris Performance in Central Texas this last week and get back on a dirt bike. I'm decent at jetting but had struggled a bit with this bike because I ... more »

The solution would be a weird wrong sized cylinder or head to mess up the displacement to get it outside of the tariff zone, with an included rebuild kit for the dealer to retrofit. What a PITA though.

I suspect you are going to find that Chevy's new 2017 ZR2 is going to be a vastly superior off-road vehicle all around. Weighing 30% less, costing 40% less, and using 35% less fuel has a way of doing that.

They are beautiful trucks (the Raptor) but it's a desert rig. If you don't use it for humming across the desert on a regular basis it's just kind of silly. And obviously the F250 is better equipped as a tow rig. ~ good luck

I rode the bike a couple of days ago. Track was tilled deep, real power sucking. I also had dropped to 13/ 47 gearing in an attempt to spread the powerband out, a gear set up that previously I could never get to work well for me as it just wouldn't pull ... more »

Well a couple of notes: - I was rained out last weekend so still have not ridden the bike since picking it up from Derek. But I'll be at the track tonight. First time on a dirt bike in darn near a year so I don't expect much out of the rider! - I don't ... more »

I like to think of it as a dead reliable, lightweight, 350F bike. I think that's a solid comparison of the powerband and ever since the stroker it's always required you to keep the RPMs up high. Really, it's just not a modern 450F. the 450s have the ... more »

Was hucking a car over blind hills on public roads. Could have easily killed a kid on a bike or something. Extremely irresponsible. From a public safety standpoint he is more dangerous than the wheelie boys by a lot.

Most Baby Boomers said that they wanted their children to have it easier than they did, and they succeeded tremendously! Until your 30 year old has to pay his own cell phone bill they won't grow up. That's animal nature to take the easy way out. The ... more »

I was happy to see him take the win last night, but he's not a 450 Champion unless he gets a fair bit faster.

Too many raging lifelong addicts just quit one day because they finally start caring about others. To say one has an addictive personality is the same thing as saying you have poor self-control and selfish tendencies as that's all it is.

At the least the chicanes should have forced the riders in to 1 of 2 lanes of equal distance to create passing opportunities.
