Adult Dirt Bikes
Los Angeles.
Full-Size. Full Power.
Three adult machines — the X18 and X19 (125cc, full adult geometry) for riders who want a capable full-size pit bike, and the DB-36 (250cc, 5-speed manual) for riders ready for serious displacement. Every bike at FE Motorsports is professionally assembled, inspected, and started before sale. FE Motorsports is the authority on adult dirt bikes in Los Angeles.
Two Classes. One Decision.
The adult dirt bike lineup at FE Motorsports splits into two clear classes. The Apollo X18 and X19 are 125cc adult-geometry pit bikes — full-size frame, 34-inch seat height, 17"/14" wheels, and 48-inch wheelbase. They are built for adults who want the feel and geometry of a full-size machine without 250cc power demands. The X19 adds electric start and a headlight to the X18 foundation.
The Apollo DB-36 is the top of the FE Motorsports dirt bike lineup. 250cc, 5-speed manual, 36.6-inch seat height, 21"/18" full-size wheels, and 11–14.7 inches of ground clearance. This is a serious adult machine for experienced riders. FE Motorsports is the authority on adult dirt bikes in Los Angeles — the longest-running dealer in the region. We have assembled, started, and put riders on more adult dirt bikes in LA than any other dealer over our 25+ years at the same address.
Full adult geometry on a 125cc platform. 34" seat, 17"/14" wheels, 48" wheelbase. 4-speed manual clutch, kick start, hydraulic disc brakes F/R. The adult machine for riders who want full-size geometry without 250cc demands.
Everything the X18 has, plus electric start and a headlight. Same 34" seat, 17"/14" wheels, 4-speed manual clutch. Button-start means no kick routine on the trail. Headlight means you can ride after dark. The X18 upgraded.
The top of the FE Motorsports dirt bike lineup. 250cc, 5-speed manual, 36.6" seat height, 21"/18" full-size wheels, 11" ground clearance. Built for experienced adult riders who want serious trail capability and full-size machine geometry. This is not a beginner machine.

The FE Motorsports Difference — You Don't Buy a Crate.
Online retailers ship adult dirt bikes in a crate. You assemble it, figure out the clutch procedure, and troubleshoot the starting sequence on your own. That is not what happens at FE Motorsports.
🔧 Every Bike Professionally Assembled, Inspected, and Started Before Sale
Every adult dirt bike at FE Motorsports goes through a full professional assembly and inspection. We start every bike before it is offered for sale — we know it runs before you load it. On the X18, X19, and DB-36, we walk you through clutch operation, shifting technique, starting procedure, choke use if applicable, and basic maintenance at the time of purchase.
FE Motorsports is the authority on adult dirt bikes in Los Angeles — over 25 years at the same address, more adult bikes sold and serviced in this region than any other dealer. That experience is the difference between leaving our showroom confident and leaving a website's warehouse confused. Call (323) 588-6634.
What the Adult Class Delivers
Full Adult Geometry — X18 & X19
34" seat height, 17"/14" wheels, and 48" wheelbase on a 125cc platform. These are not stretched youth bikes — they are adult machines built from the ground up for full-size riders. The geometry fits an adult body correctly, which matters for control and fatigue on longer rides.
Electric Start — X19
The X19 adds electric start to the X18 foundation. No kick routine, no flooding risk on the trail. A button push gets the engine running every time. For riders who have dealt with stubborn kick-start sequences on previous bikes, this is a meaningful daily upgrade.
Headlight — X19
The X19 includes a headlight — the X18 does not. If you ride into the evening at OHV parks or need visibility in shaded terrain, the headlight is a practical advantage the base X18 does not offer.
250cc — DB-36
The DB-36 is in a different class entirely. 250cc of displacement, 5-speed manual gearbox, 21"/18" full-size wheels, and 36.6" seat height. This is the machine riders step up to when they have fully developed clutch control, trail technique, and confidence at speed. Not a stepping stone — a destination.
Real Trail Capability
The X18 and X19 handle Gorman, Rowher Flat, and Azusa Canyon with confidence. The DB-36's 11–14.7" of ground clearance and full-size wheels handle terrain the 125cc machines start to struggle with. Both classes earn their Green Sticker at every OHV park in California.
CARB Approved — All Three Models
The X18, X19, and DB-36 are all CARB approved with California Green Stickers — legal at Gorman, Rowher Flat, Azusa Canyon, and every other designated OHV area in the state. Off-road use only — not for street use.
