I am selling a 2010 Yamaha YZ450F. I rode the bike for about two years. I have another dirt bike that I have put time on the past two years so the 2010 mainly sat other then me taking it out a few times to keep the seals and what not from drying out. I need to get rid of the bike since I do not ride it anymore. I bought the bike with only 3 hrs on it and have always kept up on the maintenance. Changed oil every 3 rides. Changed the air filter every ride. The only thing I had done to the bike was a suspension re-valve for a rider who weights between 180-200lbs. Serviced the suspension before I quit riding the bike as well as took the engine apart to make sure everything was within spec which it was so it's ready to ride. Every part I ever bought for the bike including the engine parts have always been Yamaha OEM parts. The bike has normal wear on it and probably has around 70-80 hrs on it total time. I believe I have a few extra parts for the bike laying around such as plastic and potentially a FMF silencer. No trades please. I'm asking 3,400, but may consider other offers. I have the title. Cell: 765-418-5227 Thanks, Stephen

I am selling my baby, no seriously, I have loved this bike more than anything else over the last 6 years. But alas, it is time for me to say goodbye. The reason I am selling is because I have found a new love and need the $$ to free her from Bobby J's yamaha. Here is the scoop: I bought this bike, brand new from the dealer in 2008--so only 1 owner. Since that time, I've added a TON of aftermarket parts and accessories, most of which will not transfer over to the new bike, so I prefer to keep everything whole. Here's a list of the new parts: 1.) Aftermarket Muffler Sparky with the screen removed (but will be included if you want it). 2.) Aftermarket front/rear brake covers. 3.) BFM Offroad full graphics kit 4.) ASV unbreakable levers 5.) Trailtech Vapor computer (tachometer, odometer, water temp, total miles etc) 6.) Trailtech computer mount 7.) Trailtech HID headlights with stand-alone battery packs 8.) New front/rear inner tubes 9.) New front/rear tires 10.) New front, rear, shock, steering stem, lower, & swing arm bearings (All Balls--the good one's) 11.) New front fork seals 12.) New front brakes....not yet installed 13.) Protaper fatty bars 14.) New aluminum (unbreakable) throttle tube with bearings 15.) New grips 16.) O-ring chain 17.) Stage 1 jet kit, new needle 18.) New fuel screw I'm sure there is more that I am forgetting, but those are the one's I recall. This bike has NEVER been raced, only owned by someone who loved it very much and I would like to see it go to a good home. I have all the reciepts for everything I ever bought and installed on the bike. Bike was always well taken care of, oil changes every 3 rides, air filter cleaned every ride, only premium fuel run, never put away dirty. These model year YZ's are desirable because many people still do not trust the new fuel injected systems and these are known to be nearly bullet-proof. This bike is carburated and can be jetted for any altitude. It is currently jetted for around 6000ft and pulls like a freaking tractor. It's always done everything I asked it to, including hills that seem to go up for miles and mud and sand that just won't quit. Excellent all around bike. Willing to deliver for $.30/mile round trip. Bike located in Albuquerque, NM 87108

WE'RE OPEN 7 DAYS A WEEK! Ask for JOSH! Brand NEW 2014 YAMAHA YZ450F $7,547.32 - OUT THE DOOR, NO TAX** CALL/TEXT JOSH 1-740-296-9653 Email me DIRECTLY - [email protected] CALL TOLL FREE - 866-392-4531 WE SPECIALIZE IN HIGH VOLUME & MULTI UNIT SALES THE BUY IT NOW AND RESERVE ARE $7,547.32 **All rebates and incentives have been applied to the purchase price of the unit. KEY FEATURES: · YZ450F’s revolutionary rearward-slanted-cylinder design is an innovative approach to achieve unmatched mass centralization. Concentrating the motorcycle’s heaviest components (engine mass, fuel tank, exhaust system, and airbox) toward the center of the machine helps achieve superior, nimble handling. · The 4-titanium-valve cylinder head is matched to a newly recalibrated fuel injection system to provide superb power feeling across the rpm range. The adjustable fuel injection system uses a 44mm throttle body fed by a high pressure battery-less electric pump to ensure optimum fuel atomization and air/fuel calibration for excellent readability in a wide range of riding conditions. The YZ450F instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions. · The new aluminum Bilateral Beam frame offers a superb rigidity balance and, with new settings to already class leading front and rear suspension, provides unmatched lightweight handling and cornering. For 2014, the steering head pipe is moved 10mm closer to the rider, making for a more compact chassis dimension and placing more weight bias on the front wheel which translates to an even more precise and instinctive handling character. · Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons. · “In-mold graphics” technology is a method in which the graphics are molded into the radiator shrouds for improved decal durability and reduced scratches. ENGINE: · For 2014, the top-end... Piston, intake and exhaust valves, ports, valve mechanism, ignition timing, and fuel injection mapping have all been meticulously revised, resulting in improved combustion and outstanding engine performance throughout the power band, with a focus on controllability. · The new high-performance ECU provides great bottom end torque plus delivers a strong feeling of power from 3rd gear up while new gear ratios also lengthen the powerband and heighten the feeling of power in 2nd and 3rd gear. · The valve mechanisms and cylinder head feature new specs that take performance to the next level. Intake and exhaust valves are enlarged and the cam profile for the intake has been modified, all contributing to improved combustion, resulting in added power and outstanding performance. · The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaust pulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This new layout allows the silencer to be positioned 186mm further forward behind the side panel, closer to the middle of the bike which centralizes the mass for superior handling. · The compact wet sump lubrication system with piston cooler spray jet eliminates the need for an oil tank, reducing engine weight. The water pump employs a plastic resin impeller for further weight reduction. The reduced size of the crankcase enabled by this lubrication system design is a major factor in making it possible to mount the 450cc engine on the newly designed compact frame to deliver precise and instinctive handling. · Newly designed transmission and shift mechanisms provide quicker, smoother shifting under power with less effort. · The accessory GYTR Power Tuner can simplify the work of adjusting fuel injection volume and ignition timing settings to fit personal preferences or track conditions. CHASSIS/SUSPENSION · A newly designed aluminum Bilateral Beam frame is adopted in which the head pipe is moved 10mm closer to the rider. The overall dimensions are roughly the same as the frame of the 2013 YZ250F. This gives the YZ450F a new compact chassis that provides the most instinctive handling in the 450 motocross class. · The aluminum muffler is positioned closer to the machine’s center of gravity as it is almost completely hidden by the side number plate. The layout allows a shorter, lighter sub frame and also contributes to mass centralization for lightweight handling feel. · The front suspension has proven KYB® air-oil separated forks. It adopts new spec inner and outer tubes coupled with optimized suspension settings. The new rear suspension also features a new reservoir location and spring spec with settings optimized for ideal damping characteristics to match the new chassis dimensions. · The new larger diameter 22mm front axle and new top triple clamp increase rigidity for improved handling and front end feel. The handlebar mounts are now rubber mounted to improve comfort and reduce handlebar vibration. · A new layout for the fuel tank and air cleaner box gives the machine a slimmer feeling between the legs as well as positions fuel tank mass closer to the center of the bike which improves handling feel. Furthermore, the air box can now be accessed without removing the fuel tank for easy serviceability of the new larger air cleaner element. · A new narrower radiator design contributes to slimming down the radiator panel area.

Instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions. The aluminum Bilateral Beam frame provides a superb rigidity balance that complements the engine for unmatched lightweight handling and cornering. The result? The best cornering, most nimble 450F for all track conditions. Revamped looks deliver new-generation styling, including front and rear fenders, intake cover, front fork protector, and number plate, along with the fuel tank and seat. Accessory GYTR® Power Tuner lets bike tuners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions. Features & Benefits New For 2011 New clutch lever and pushrod for more consistent clutch feel during long motos. Engine The rearward-slanted engine allowed engineers to design straight intake and exhaust ports, creating the most direct path for air flow into the fuel-injected engine for incredible performance. The YZ450F uses a battery-less fuel injection system with a12-hole injector for superb fuel atomization. The 44mm Keihin ®throttle body is designed for easy starting, with an integrated cold start and idle speed adjustment knob. Yamaha FI provides optimal air/fuel mixtures in all altitudes and wide range of temperatures for outstanding throttle response. 14 volt / 110W high output generator powers the battery less fuel injection system. 4-titanium valve cylinder head with a "pent-roof" design combustion chamber provides excellent combustion efficiency and unequalled power output. Intake and exhaust camshaft profile changes to increase valve working angle and valve lift for most excellent performance at all rpm.
