How fast does the FRP FX140 go?
65 mph top speed, with up to ~155 miles per 1.4-gallon tank. Real-world speed depends on rider weight, terrain, and gearing.
What engine and power does the FX140 have?
A 140cc 4-stroke oil-cooled engine making 11.0 hp (8.2 kW) @ 7,500 rpm and 10.2 N·m of torque @ 6,000 rpm, with electric and kick start and hydraulic disc brakes front and rear.
FX125 vs FX140 — which should I choose?
In the 17/14 build they share a chassis: same 33.9″ seat, same 49.2″ wheelbase, same 265 lb load rating. The difference is the engine. The FX140 is oil-cooled, makes 11.0 hp and 10.2 N·m against the FX125's 8.7 hp and 8.8 N·m, and is rated to climb 30° versus 28°. Oil cooling is what holds that power up on long climbs, hot days, and hour-long sessions, where an air-cooled engine starts to fade. For short sessions in the yard, cooler weather, or a lighter rider, the FX125 is enough.
How tall is the FX140 — what's the seat height?
Seat height is 33.9″ on a 49.2″ wheelbase, with 17″ front / 14″ rear wheels — the same seat height as the FX125 in its 17/14 build.
Who is the FX140 for, and what age?
Teens and adults — bigger or more experienced riders, up to a 265 lb max load. If you're new to off-road, start on a smaller bike like the FX125 or FX40 first.
What is the weight limit on the FX140 — how much weight can it hold?
The FX140 supports a 265 lb maximum rider load. The bike itself weighs about 170.9 lb.
Is the FX140 a pit bike or a dirt bike?
Both names get used — it's a full off-road dirt bike, often called a 140 pit bike. It runs an oil-cooled 140cc engine with a 4-speed manual transmission.
Is the 4-speed manual hard to ride?
It's a 4-speed manual with a clutch. It's a new skill if you're coming off a no-clutch bike like the FX40, but most riders pick up the basics in an afternoon on flat ground.
Can I ride the FX140 on the street?
No. It's EPA off-road only — built for trails, private property, farms, and open land. It is not street legal.
Is the FX140 available in California?
No — the FX140 is not sold or shipped to California (Prop 65).
What brakes, suspension, and starting does the FX140 have?
Hydraulic disc brakes front and rear, long-travel suspension, and electric start with a kick-start backup. It runs on regular gas with no oil mixing.
How much assembly does the FX140 need?
It ships mostly built — about 30–45 minutes with the included tools. Setup videos are in Service Videos & Tutorials.
How does the FX140 ship, and what's the warranty?
A 1-year limited warranty. It ships within 72 hours via LTL freight. Freight delivery is curbside and the carrier calls to schedule an appointment, so give a valid phone number and email — plan on help getting the crate off the curb. Not shipped to California (Prop 65), U.S. protectorates, APO/FPO, or overseas. The box includes the First Ride Kit: gloves, goggles, anti-fog spray, backpack, hydration bladder, tools, and the manual.
