Here is an even better deal directly from Pitster Pro, but not sure if shipping changes that.

Chonda, does it seem to you that a skid plate that would fit from the KTM model that you used for your tank or even one of the four stroke models that use the same frame?

Probably... the stock skid is pretty good. So, I haven't really considered it.

I'm currently a few hundred miles from the bike or I'd take a closer look.

Went into Pitster Pro today and picked up a front brake lever and shifter. While there I showed them some pictures and asked about getting access to the EFI tuning at a deeper level; the head guy wasn't there, but the parts guys said that they are actively pursuing a way to make tuning changes.

I volunteered to be a tester/Guinea Pig. Hope they make it happen. THAT would take this bike to another level.

Now that I have a way to safely do so; with stock 13/51 gearing the Pitster Pro LXR250 EFI has a top speed of 76 mph on a hot day at 4900ft asl. Temperature was about 98 F most of the time. Too hot for me.

I'd wager that it would eek out a few more mph on a cooler day or lower altitude, but it was near the rev limiter.

Tried out my 15t front sprocket today. This is the sprocket you want for making this bike a good all-arounder. It still has good take off power, but cruises at 45-65mph so much better than the 13/51 stock setup. No doubt one could ride all day at 65mph with no issues.

I ran down to the interstate by my house to see how much the 15t sprocket helped top end speed. Here's the stats: 260lb rider, 15/51, altitude 4900 or so, 86-88F temp, top speed attained was 79 mph. Going the other way there was a stiff headwind and the best I could do was 76 mph. No doubt a smaller rider could hit 80+.

Sprockets are the same as a Suzuki DRZ400. PBI 650 series is my preference. I have a 650-15 and a 650-12 now. The 15 fits with no clearance issues except a small piece of plastic from the chain wear guard that needs to be trimmed off:









This is probably the fastest I will ever ride this bike. It handles well on concrete freeway with lines in it, but this is not what the bike was built for. The less slab I ride the better, plus I prefer 60 mph cruising speeds. More than 60 is just too much wind, noise and vibration.

Vibration at speed is a concern. The bars do vibrate more than I like. Is it possible that it may calm down as it breaks in??

[Adjuster]

Do you think the vibrating is coming from engine, tires or wind? A simple thing to try. Next time at speed sit a little farther up on the seat and tuck in a little more. Try to get a little more weight at the front of the bike.

Definitely the motor.

It's a high rpm type vibration, not correlated to wheel speed at all, but to rpm.

sound like most 250cc 4t singles.... it's what they do....

PS.... like the alloy frame around the trail tec... can you get them for all models...

Yes, it is what they do. I'm getting old...


I do believe you can get something similar for all the trail tech stuff. My wife's bike has an older Vapor with a simpler alloy frame mount.

Installed some anti-vibe brass bar inserts last night. Unbelievable difference at idle. Can't wait to fully test after I get the radiator back from the shop.

I ordered the brand Highway Dirtbikes - they are designed for use with their handguards, which I bought about 10 years ago and keep moving from bike to bike- because it simply the best rear view mirror/handguard setup I have found.



So they are made for these handguards, but should work with any others.
