AlpineStar Tech 8s My favorite boots just got a lot better. The Alpinestar Tech 8’s are now over one pound lighter(less weight hanging out there and potentially less stress on knee). They have much easier to use buckles, better soles and extra hard plastic on the right boot where you hit the foot-peg when

Hot Rods the Original cranks and Rods now gives you KTM Complete Crankshafts. KTM owners pleaded and yelled loud enough that we listened and have a full line of complete crankshafts for KTM’s. The models now in stoke are for the two strokes (125SX, 200XC, 250SX 250, 300MXC) and four stroke (250SX-F 2005-2010). The complete

I have been using Uni filters for over 20 years now (yes I am old) and they never let me down. Also they have any crazy size filter you could need. Here is a pod that we used on a little race quad. You name it they got it. Uni Filter www.unifilter.com 714-535-6933
There is no suspension company that is as diverse as Race Tech who works on ATV’s, Street bikes, vintage and of course dirt bikes. When it comes to something odd-ball they will fix it up. Here is a TTR Shock that needed help with a shaft they got fixed up. Race Tech www. racetech.com 951

The new CRF250R’s are fuel injected and a complete new engine. Travis at Thumper got one to 280cc with a big bore and a stroker version out to 300. We did the 264cc version here. Tested one day at racetown and one at Piru and had about eight different test riders all love each of
Parts Unlimited magazine got to test the best mods on a current CRF450R– Hot Cam and high comp piston. Josh Brown for testing riding and Kenny Jones shooting the pics. Came out great!
Tom Morgan at Hot Cams came up with great cams and mapping to put this mod on top of MXA’s mini-test a few months back!
Last minute Hot Cams got Kiniry to fly out from New York state and give it a shot and see the Racer X project bike through.
He came up short the Sunday before the National on a section they ended up taking out for the race. Bummer deal—
We tried for the last national but go hurt so had to go Johnny Jeldera.
These come in the already proven wheel bearing kits and have an o-ring on the inside diameter of the spacer so that no water gets in to the axle/bearings.
A simple drop-in kit that really works!!! Combined with a Hot Cam and FMF pipe.
Great mod by Travis at Thumper!!!!
Last year we went for the 470 big bore but this year we kept it stock bore and hit a homer with this full CV4 mod.
CP made the Custom pistons, Race Tech took care of the suspension and Bennetts Performance put it all together. FMF made custom pipes with self tuning Dynojet power Commander. Will be in Cycle World shortly.
Here is a picture of the Cylinder Works 269cc kit that works on all 2001-2011 YZ/WR 250’s. This is the best mod for your money on a YZ/WR 250. Only $599.95 Cylinder, piston kit and gaskets!
Fits all current YZF250’s and either the cylinder big bore kit alone at 269cc or stroker to go to 284cc — This one was for Moto USA
Transworld Motocross just tested the latest beast I created. Fast Core Mods did the head Work, Millennium the big bore cylinder and CP the high compression piston.
280cc big bore with a CP Piston, FMF Pipe, Millennium Cylinder plating and Thumper put it all together for Cycle World.
Brian at SRC worked with Thumper Racing to make the fastest thing we have ever riden. Josh in his Fox gear is a Quad pro now!
Stock is 76.8mm and big bore is out to 79mm making it 264cc and the results are great! Big power gains for low cost in the new CRF250R with no fuel mapping changes.
The Honda 400 motor is proven but can just use a bit of a boost from a cam and piston. Hot Cams and CP took care of that with a FMF pipe.
