Up-Tite Throttle Tube

Just got this in the mail. George likes to send packages COD. He is definitely Old School. I called him and ordered it and he needed the ID of the handle bar because he needs to machine the insert for the end of the handle bar (silver thing in the picture). Basically the insert has a barring on the end of so the end of the throttle tracks nice and smooth. After cracking my throttle tube in Baja, hs showed me the one on his bike and let me feel it and it feels WAY smoother than the stocker. I'll let you all know what I think about it after this weekend's ride.

You will love it! It takes all the numbness out of the throttle hand. Just be careful and grab to much of it....that tube will throw you for a loop.

It removes vibration? Sorry if that's a dumb question.

How much is it if you don't mind me asking?

drastically removes vibs.

I cannot remember the exact amount. Call George and he will fill you in on the rest. This tube is a work of art.

Can you use it with wrap around hand guards?

Ask George...he was working on something. I removed the bearing on mine and the tube is still better on vibes than the stocker. I cut the last 1/8" off mine and it works great. Maybe he can sell it without the bearing and let you do the mod yourself.

Whats wrong with the bearing?

I have a bearing tube, not Georges, and use hand guards. I also use A-TEK threaded insert in the bars for mounting the guards, I don't use the bushing and use a bolt in it's place. I run a shim on the inside of the center race and a bushing with a flanged end on the outside for the guard to bolt against. It pinches the center race and allows the tube to ride on the outer race.

You can actually put a bearing in any throttle tube. I used one with the stock plastic tube, but you'll get the most if it has a teflon or delrin bushing toward the cable end.

I took my bearing out when I installed my zetas. I mentioned this for those that plan to run guards.

I have a brand new unused George tube identical to the one pictured on my shelf beside the computer.

Not to jack a thread, I'd barter it for something...perhaps an air filter?

lets get under coffees skin and barter this in public.

ive got an airfilter for that tube.

This weekend was AWESOME! I just got my bike back together after having the suspension redone by Les at LTR. I completely went through the bike while the suspension was off, lubed everything up and cleaned everything, etc. The new Throttle tube worked AMAZING! I couldn't believe the difference after putting it on. The throttle is sooooo smooth now and because of the way George designed it I can go from idle to WOT with the flick of my wrist. Between the new throttle tube and the new suspension I have fallen in love with this bike all over again. When we got back last night, I had to convince my girlfriend to go out again with me next weekend. I really had a blast on my "new" bike.

Someone has to walk me through putting this thing on with my wrap around Cycra's! Sounds great Blake and thanks for the heads up.

David,

I'm not sure how that would work. I'm not running hand guards right now. I think you would have to loose the bearing and cut off the end of the tube. Even though the center of the insert is tapped to hold the bearing, It's not a very big hole for the bolt to hold the guard on, and I think one good whack with a tree/rock/ground on that hand guard, could really screw up some stuff and possibly leave you with a stuck throttle to get back to the truck. Give George a call. He may be able to do something custom for you. The big difference is the shortened distance from idle to WOT. It took about 30 seconds of riding for me to get used to it, but now I have precision control.

I like the idea of shortened distance from idle to WOT and the precision throttle control with the bearing!

Have any of you guys ridden in tight tech stuff with that tube yet( I'm talking about 1st gear mud covered rock zones and going over 2 foot dia logs and scraping your handle bars going between trees everywhere you go. Thats what I consider tight). It would probably be OK on smaller bikes in the tight stuff, but it seems it would be really hard to control a 450 in the tight stuff with that throttle tube.

I cut the last 1/8" off mine. The end of the throttle tube needs to be indexed a little. It works great and after two races I have had no issues.
