Sometimes money is no object.

And if the world were perfect every dirt bike rider would have access to the best and finest aftermarket products available, alas only a lucky few get that shopping spree. Unless you're racing in the "Limited" class you'll need some performance gains to make you competitive on the track. Beginners tend to start out slow and grab as much performance perks as possible without spending a lot of money. (Check out 12 Inexpensive Adjustments to Improve Dirt Bike Performance.) But once racing really heats up and you're hooked to the drug called podium you'll want more.

It's going to cost you.

To truly compete in a Pro class or even B class you'll need to upgrade some components on your bike and if you've got the means, it's best to go high-end right away.

Be forewarned, if you've just starting looking into higher end parts for your dirt bike, the sticker shock can be unsettling but nothing a couple of holeshots and a few wins can't pay for.

Rekluse Clutch Kit

This is number one for a reason because it's the #1 upgrade you can do to your dirt bike - above anything else on this list. Some riders call the Rekluse Core EXP 3.0 Kit PEDs for your dirt bike, but legal! The Rekluse is expensive - $630 to $900 - but it's well worth the investment. Watch lap times soar, corner on rails, better starts and an overall boost of your confidence on the bike.

Alternative: Some riders love the manual clutch, if so, grab the Rekluse Torq-Drive Manual Clutch Kit. Same type of response as its automatic brother, but you do all the work.

Myler's Radiator Combo

In many respects the Myler's SuperCool Radiator Combo offers two layers of protection. The first, of course, prevents the engine from overheating something we see all summer long. But the toughness of the Myler's Radiator withstands a crash or spill over much better than stock. You're looking at about $300 but if you're not steam cleaning your front fender after a crash you're money ahead.

Exhaust System

FMF Factory 4.1 RCT Compelte Exhaust with Titanium Megabomb Header. Need we say more? OK, it's more than $1,000 but you're riding with the factory guys now.

Power Assistance

Gain valuable lap seconds on your competition by installing the GET Power ECU combined with a GET GPA Switch. This is the best money can buy (combined more than $600) to tweak the dirt bike's engine power based on your riding style and track conditions.

Holeshot Device

The most affordable item on this list the Devol X-Shot Holeshot System is just $100 and only adds 2.4 ounces to your dirt bike. No more loop outs! In fact, many riders keep this on long after they've gone pro.

Plastic

How can a new plastic kit improve the performance of your dirt bike? When you use a style lighter than the rest and designed to increase the bike's aerodynamics. Cycra did all this with their inventive plastic kit. Think of these as nickel and diming your way to the podium. Every bit of edge counts. A full kit sets you back between $135 to $220.

Chain and Sprocket

The only problem with putting a Sunstar Chain & Works Z Sprocket Combo on your dirt bike is they look so beautiful you won't want to get them dirty. But once you find out the performance gains and the extreme durability it offers, you won't care because holding a check is way more photogenic. When choosing your chain option, grab the Sunstar XTG Tripleguard and you'll more than make up for the expense over the long run. Price varies between $143 to more than $260.

New Brakes

You want a faster lap time? Then you'll need some of the best brakes in the industry. The MOTO STUFF Blade Oversize Brake kit is the dirt bike equivalent to a car's Anti-lock Braking System. These oversized rotors weigh a pound lighter than other equivalent systems and last longer which helps make up for the $300+ price tag. By the way, Team Honda and the GEICO Factory Connection team use them on their bikes.

Big Bore Kit

Probably second to the Rekluse Clutch kit for return on investment, upgrading your dirt bike's engine displacement delivers so much power you'll wish you had done it sooner. The cost varies from as low as $250 to as much as $2,000. Ask our Gearheads for help if you need it.

Wheels

Tired of bent rims every time you come up short or overshoot? Well then learn to ride! Ok, just kidding, even the pros calculate wrong every now and then but they don't limp back to the pits because of inferior wheels. Truth is, cost keeps most riders from addressing their wheels right away which is why it's on this expensive list and comes in at #10. But if you can swing it, the Warp 9 Elite combo gives extreme durability and look really cool.

These are all the big ticket items worth pursuing as you work your way through the amateur and pro ranks but the list of upgrades doesn't end here. Tires, handlebars and controls, and of course, the fortune of adding a brand new suspension tack on hundreds if not thousands of dollars more.

As you can see, shelling out the cash for all the above costs as much as a new dirt bike. Though some are must-haves in order to seriously compete others you'll find just don't complement your riding style or provide extended comfort on the bike. Therefore you might get away with a less expensive part that frees you to install that Rekluse clutch.

And even if you're not one of those blessed with a money tree in your backyard, you'll find a way to step up your game come race day, pull the holeshot and take your winnings to piecemeal your bike to a Championship.
