My ride of choice is a 2002 Polaris Scrambler 500X model heavily modded with bolt ons, internals, and physical appearance.
Here are the things ive done to it

Stock horsepower; 42-45 Hp.
Dry weight stock 530 pounds
Special Features from Factory:
Black fenders, body, Special Decals and black/graphite vinyl seat cover.
Aluminum front Bumper
Cross-Drilled and Slotted Brake Rotors Front & Rear, with Braided Stainless Steel Brake lines.
Upgrades and modifications I have had installed or performed:
Exterior/ Physical Appearance modifications - Most all these done by myself.
1. Weight Reduction:
Trimmed/shaved Fenders ferrings
Removed All unnecessary guards, lighting, housings, containers, Foot plates, Foot operated brake pedal.
Replaced bulky Steel foot pads, with custom Diamond brite aluminum pieces, also replaced headlight bracket with custom Aluminum bracket.
Shortened CVT Shifter lever, so it doesn't protrude from atop the front right fender,
Replaced factory shifter knob with brushed aluminum one.
Shaved factory seat foam, reducing overall seat height by 50-70%. To lower riders' center of gravity and allowing for more aggressive riding postion
T6061 Moose one piece under-chassis skid plate.
Hot Seat performance low slung ALuminum Handle Bars, with grips. For better riding position
2. Suspension/Tire-Wheels/Brake Upgrades-Modifications:
Suspension: HOT SEAT PERFORMANCE - Light weight and 2.5 inch extended rear swing arm with Polished Nickel plated finish. "OUTERWEAR" shock socks covers both F-R
Tires/Wheels: Dirt Tire Set - ITP Polished Aluminum rims F&R, fitted with 20x11x10 MAXXIS-MX-RAZRS on the Rear, and 21x7x10 MAXXIS iRAZRS on the front
Sand Tire Set - ITP Polished Aluminum Lightweight rims F&R. KENDA 21x11x10 SAND GECKOS on Rear and KENDA 22x8x10 DUNE RUNNERS up Front.
Braking: Entire brake system redone, and customized. Removed rear brake foot lever assembly and relocated to right side handle bar using the factory Handle bar mounted Predator brake lever assembly, complete with S/S brake line.
Left hand Brake that originally applied braking force to Front & Rear simultaneously, was modified so that it only operated front braking system. Resulting in having all brake operations on the handle bars. the left brake lever for front braking, and right brake lever for rear braking.
3: Intake/Exhaust/Engine
Intake: TMX 42mm Carb. HPD Mass Air Intake airbox lid modification. K&N filter. OUTERWEAR filter sock

4: Transmission/Drivetrain
Transmission: HPD Aggressive Clutch engagement kit, basically it allows the transmission to engage at 2500 rpm, rather than stock rpm of 1200 or so. and allows for easier smoother back shifting as well.
Drivetrain: SIDEWINDER Ti-Moly Initial/Final Sprocket set. 9-11/36 (Initial/Final tooth count). with 520 O-ring Chain. Came as set. HPD ctc, concentric chain tensioner.
