If you work at Rocky Mountain ATV/MC, chances are you have a machine you’re working on or one you’re saving your paychecks for. Most everyone here has the itch to ride and an even bigger itch to keep up with the latest and greatest machines the industry has to offer. That said and with the rotation of so many new models and bikes coming out every year, we get our fair share of chances to ride, test-fit parts on, and just get experience with most new machines. So, when one of our team members picked up the new 2020 YZ250FX, we couldn’t wait to start personalizing the bike. We needed the bike to be versatile enough to tackle single track, desert races, technical terrain, and the occasional motocross track. With the bike’s performance, controls, and protection as our main focuses, we got to work.

Performance

Our build first focused on various areas of performance. No doubt the bike is a performer, but there were a few areas we wanted to make better. After nailing down our first impressions of the bike and getting some significant seat time in, we realized one persistent problem: often times the bike didn’t want to start. The bike wouldn’t even click – we’d have to shift into neutral and rock it back and forth to get it firing back up. With a little research, we realized we weren’t the only ones having this problem and the bike’s stock battery was likely the culprit. Some customers have had the stock battery perform flawless, but ours had an issue. Installing the Tusk Lithium Pro Battery was the first improvement we made to the stock 250FX.

With the main (and really only) issue with the bike taken care of, we moved on to the more personalized upgrades we needed to make. That started with a spark arrestor – one is required for the areas we ride. FMF’s 4.1 Anodized Exhaust System with a Carbon End Cap gets the job done and looks good doing it. The spark arrestor has a great sound and doesn’t cut out performance – on the contrary, we noticed a slight increase.

Popping a Wheelie on the YZ250FX

Another important factor in steep hill climbs and technical trails is cooling. Like most other riders, we like a little peace of mind when riding, and the Tusk Universal Radiator Fan Kit gives us just that. By setting a starting temperature on the fan kit, we can trust that it will kick on and give our engine some relief during those slow, technical climbs where airflow may be infrequent or inconsistent. And just to keep the coolant flowing well, we switched the stock radiator hoses for those in the Tusk Radiator Hose Kit. We’ve found the Tusk offering to be more durable than stock, and their color options give every bike a factory look well below the factory price.

Controls

Our focus then shifted to the YZ’s controls. The first modification we made here was to the handlebars. Everyone’s riding style and level of comfort is different which means the stock handlebars should always be assessed at the very least. After riding on ours, we decided to install some Fasst Flexx handlebars. We’ve been more than satisfied running the Fasst Flexx bars on other bikes and have found that they absorb vibration well, so it was an easy choice for us. We’ve even noticed that we have less soreness, reduced arm pump, and minimal fatigue after just a few rides on the new bars.

Working our way out from the bars, we decided to install all new levers as well. Plus, if you have a hard time keeping your bike on two wheels like we sometimes do, you’ll have the opportunity to invest in breakaway levers like we did. We opted for the ASV C6 levers. They perform as well as we could want and have a 6-year warranty as a bonus. Plus, they look great on the bike and feel great while riding.

Capping off our bars are the ODI V2 Emig Pro Lock-On Grips. In our opinion, these are some of the best grips you can get. Their lock-on design makes them easy to install by eliminating the need for grip glue. Every ride without fail, the grips absorb vibration and keep our hands comfortable.

Showing Off the New Handlebars

With all of our new controls installed, specifically the handlebars, we realized that we didn’t have much space left up front. Since we still needed a spot for our start and kill switch, we opted for a mounted perch switch. It gave us a spot for our switches and space for the levers and handguards we wanted to install.

Moving down the bike, new foot pegs were in order. The Fasst Impact Moto Pegs fit perfectly. Not only are they wider than stock, but the Fasst Impacts are replaceable as far as the cleats go. Their design also helps them absorb vibration and impacts, making them especially useful on the rough, technical, and hard terrain we frequent.

Along with the new foot pegs, the inexpensive yet effective Tusk Aluminum Brake Pedal and Shift Lever were both installed. They are consistently high-quality and even come in cool colors. Speaking of cool colors, a Dirt Tricks Zirconium Rear Sprocket was a must-have for our YZ. You’d be hard-pressed to find anyone who doesn’t think the Dirt Tricks sprocket looks amazing. The sprocket is also a high-performer – Dirt Tricks designed it to last 6x longer than a traditional aluminum sprocket. Paired with the Primary Drive Gold X-Ring Chain and Steel Front Sprocket, our build was really coming together.

The Built Bike

Keeping our momentum, we made an adjustment to the last point of contact: the stock seat. Going from a stock seat to a new seat with a seat cover is a night and day difference. With our new seat and an Attack Graphics Seat Cover, we felt completely at home on our bike. A customized setup like this, especially with a gripper seat cover, can even help reduce arm pump as you don’t have to grip the bike as tightly.

Some new tires, the Tusk Hybrid Recons, were a quick performance part we couldn’t resist adding. The tires are highly-rated and highly sought after for their versatile capability in varied terrains and exceptional handling in the tricky rocky parts.

Protection

Heat shields were the first protection pieces we needed to add. Yamaha’s stock shields were weak and too easy to bend, and we knew we needed something more reliable and durable. P3’s Exhaust Heat Shields were the easy choice as they’re lightweight and offer maximum coverage. Next on the list, radiator guards were installed. To keep our radiators protected from front and side impacts alike, the Bullet Proof Designs Radiator Guards offered optimal protection while still allowing us to use our radiator fan kit.

Showing Off the New Skid Plate

It’s a known fact that Acerbis does a great job making plastics and protection pieces, and that’s why we trusted their X-Ultimate Handguards, X-Grip Frame Guards, and Chain Guide and Slider Kit to round out the protection features on our YZ250FX.

Finishing Touches

With the essentials taken care of, we had just a few extra finishing touches to add to the bike. A custom Attack Graphics graphics kit topped our plastics off for looks and protection, and a few Tusk bling parts like Front and Rear Brake Reservoir caps and Billet Brake Disc Guard added some factory-freshness on a budget.

The Finished Bike

With everything installed on our YZ250FX, we knew we’d taken an already great bike to the next level of performance, protection, and handling. We couldn’t be happier with the results and plan on ripping the bike for many years to come.
