THE 2-Stroke Piston Kit: Wiseco Racer Elite

How To Measure Your Dirt Bike's Piston To Cylinder Wall Clearance

Details

    Wiseco introduces the Racer Elite series pistons. The pistons were designed for the serious rider or racer looking for the best performing shelf piston they can find.

    Racer Elite 4-Stroke pistons feature an asymmetrical skirt design that keeps contact with the cylinder wall minimal, as well as keeps the weight down. They also feature ArmorGlide skirt coating, ensuring friction is staying as low as possible. Racer Elite 4-stroke pistons are fully machined billet, allowing for the best weight optimization and the ability to machine the boxed under-crown structure with precision.

    Racer Elite 2-Stroke pistons are forged out of a 2000 series alloy that offers more tensile strength than the more popular 4000 series. Pistons are coated with ArmorPlating, a Wiseco surface treatment covering the crown, ring groove, pin bore, and under-crown. ArmorPlating protects against wear caused by heat and detonation. ArmorFit skirt coating adapts to the proper piston-to-wall clearance during initial operation, and remains at that clearance, reducing operating friction throughout the life of the piston. A unique benefit of having ArmorFit on a 2-stroke piston is the ability to eliminate the need for A, B, C piston sizing.

Why have you not bought it yet?!?
Only piston i will run in my yz250. I change it every 20 hours in my race bike just because i am OCD about my bike but then 9 times out of 10 it has more then enough life that i throw a new ring on it and put it in my practice bike!

Terrible in a KTM 150 SX
I've used Wiseco pistons in KX 125, KX 144, RM 134, and KDX 220 and been happy with them. Tried the Racer's Elite in our '19 KTM 150 SX and it was terrible. Even though the X spec was correct and the little dome in the center should raise compression, we got LESS compression and the powerband just totally went away. After 3 hours, we pulled it and put a Vertex (OEM) 2-ringer in and bang.... everything was normal again. I have no idea what the issue was but it did NOT work well in our application.

Good quality product
I have had good luck with these pistons since I have been using them. They are a better quality than most of the competition, but a bit more expensive. I would rather pay a little more for a better product.

Piston has one ring groove. only last a few hours then needs replaced. claims to provide more power due to the friction reduction. its not worth the money.

Worth the extra $
This piston really made my 2003 RM250 quiet again. Had a wossner for about 40 hrs and it had a lot of slap from day 1. I like the single ring too...makes it easy to install and the bike sings. I recommend for an older sleeve or a cylinder that's a little worn

Wrist pin was too long for Piston
I ordered this kit for my sons KX 85, The wrist pin is too long, not allowing room to fit the C clips in on each side.

Is this a stock compression piston (12.5:1) Or a high compression piston? Would be using it in a 2014 YZ450 set up as a snow bike running Raze nitrous. Using a high quality piston with stock compression is my only option. Thanks in advance!
james l on Jul 4, 2017
BEST ANSWER: The piston is standard bore 97.00mm, it is a high compression piston at a 14:1 ratio, asymmetric skirt, all billet machined, Armorglide skirt coating, and reduced friction, quieter operation improved resistance.
Does this piston wear faster than the regular Wiseco piston?
Ethan A on Oct 30, 2017
BEST ANSWER: It wears about the same as the regular Wiseco pistons.
Does it come with gaskets?
A shopper on Apr 25, 2019
BEST ANSWER: It does not but is a great kit to get, just be sure you don't have too much play in the crank, rod, or wrist pin bearings. RMtn. is the Best! Crashburn's Cycle-
does this kit come with gaskets?
Joseph H on Jan 5, 2018
BEST ANSWER: No it comes with the piston, circlips, wrist pin and ring. U will need a top end bearing, base gasket, cylinder head gaskets/rings and in most cases the power valve cover gasket and the power valve linkage cover gasket
does this piston use one ring or two for a 2012 kx100?
MARC D on Sep 8, 2018
BEST ANSWER: This piston kit for our 2008 KX100 had one ring, and it failed, not sure why, prolly the lower crank bearing needed replacement, it did not come with a new wristpin bearing, very disappointing
I have a 2009 rmz450 what would compression be? And can u run 91-94 pump fuel? Will have hot cams stage 2 installed at a later date
Greg V on Jun 6, 2019
BEST ANSWER: your compression will be the same as OEM piston unless you are getting a higher compression piston. The racer elite pistons I've used are all OEM compression. You will be just fine on 91-94 pump fuel with the hot cams and the piston setup.
Can I use this piston with a cast iron sleeve?
A shopper on May 9, 2018
BEST ANSWER: I would consult your builder or wiseco directly, but as long as the sleeve is sized correctly I would think a coated forged piston would work pretty well. Keep in mind it is a single-ring type piston
Does this kit incude the nitride
Coated piston ring?
BRUCE M on Mar 12, 2018
BEST ANSWER: i bought mine for a 2004 YZ125 and the piston was coated and I believe it was but am not 100% sure
does it come with a wristpin bearing?
Wyatt H on Dec 1, 2017
BEST ANSWER: It does not, that has to be purchased separately.
Whats the compression for this for a 2009 rmz450 ? just want a high comp piston thanks
Greg V on Jun 6, 2019
BEST ANSWER: This is a standard compression ratio piston.
I have a 2015 Yamaha YZ250F what compression ratio is this piston?
A shopper on Apr 17, 2019
BEST ANSWER: Compression Ratio - Actual: 14.5:1
For a 2017 RMZ450 is this a stock or high compression? If High comp, what is the ratio?
Bryan C on Jul 5, 2018
BEST ANSWER: Bore - Standard: 96.00mm
Bore - Oversize: STD
Compression Ratio - Actual: 14.0:1
Additional Info.: DLC Piston Pin
Skirt Coating: ArmorGlide
Note: Racers Elite with Asymmetric Skirt
What is the compression ratio for a 2017 crf250r? thanks
Melissa R on Apr 5, 2018
BEST ANSWER: 14.5:1
Does running this piston require the use of racing fuel? Wanting to run this piston in a 03 kx250.
Erik B on Nov 30, 2017
BEST ANSWER: This piston does not require race fuel in your 03 KX250. Your compression ratio will remain the same.
