TL;DR
If you want the higher peak-horsepower number on paper and plan to lean on a deep aftermarket, the SSR SR140TR is a proven pick and genuinely lighter. If you want an easier bike to live with day to day, the FRP Moto FX140 is oil-cooled, starts at the push of a button (with kick backup), runs hydraulic disc brakes front and rear, ships with a First Ride Kit in the box, and is backed by a US-based 1-year warranty with direct parts support. Both are real 140cc pit bikes; they just optimize for different things.
Direct Answer
The SSR SR140TR and the FRP Moto FX140 are both 140cc, 4-speed manual pit bikes aimed at the same rider. The honest difference comes down to what you value. Per SSR's listing, the SR140TR makes 12 hp at 8,500 rpm and weighs about 157 lb, so on a spec sheet it wins peak power and weight. The FX140 counters with things you feel over a full riding day rather than in a dyno chart: an oil-cooled engine that shrugs off heat, electric start plus a kick backup, hydraulic disc brakes at both ends, and US-based support if something goes wrong. Choose the SR140TR for the number and the aftermarket; choose the FX140 for the ownership experience.

Specs vary by model year, so always check the current listing before you buy. SSR figures above are per SSR's own published listing; FX140 figures are FRP Moto's stated specs for the current Red/White "Pro" build with 17-inch front and 14-inch rear wheels.
FRP Moto FX140
The FX140 is built around an oil-cooled 140cc 4-stroke making about 8.7 hp at 7,000 rpm and 11 Nm at 5,500 rpm, paired with a 4-speed manual wet clutch and chain drive. Top speed is 65 mph and, on its 1.4-gallon tank, range works out to roughly 155 miles. Max rider load is 265 lb and net weight is 174 lb, with a seat height around 33.9 inches on 17-inch front / 14-inch rear wheels.
The everyday advantages are practical. Oil cooling helps the engine hold temperature on hot days and longer sessions, which is exactly when an air-cooled top end starts to feel strained. Electric start means you thumb a button and go, with a kick lever still there as backup. Braking is hydraulic disc at both ends, and long-travel suspension soaks up trail chatter. It runs on regular gas.
Every FX140 ships as a complete First Ride Kit: gloves, goggles, anti-fog spray, a backpack, a hydration bladder, tools, and the manual all come in the box. It ships in about 24 hours by FedEx within the US. Note the compliance details: it's EPA off-road only, not street legal, and not sold in California, US protectorates, or overseas. It's backed by a 1-year limited warranty with US-based direct parts support.
SSR SR140TR
The SSR SR140TR is a well-known entry in this class, and it earns that reputation. Per SSR's listing, it uses a 140cc single-cylinder 4-stroke that's air/oil-cooled and rated at 12 hp at 8,500 rpm — the highest peak horsepower number in this comparison. It runs a 4-speed manual gearbox, disc brakes front and rear, and inverted adjustable forks. Seat height is listed at 32 inches and weight at 157 lb, so it's both a touch lower and meaningfully lighter than the FX140.
SSR's biggest strength isn't on the spec sheet at all: it's the ecosystem. SSR is an established name with a deep race and aftermarket parts network, so if you like to modify, tune, and source pattern parts easily, that community support is real and worth weighing. The trade-offs are that the SR140TR is kick-start only (no electric start), SSR does not publish a top speed for it, and MSRP is about $1,959 before freight and destination. Support runs through SSR's dealer network, so the experience can vary by dealer.
The honest split: SSR wins the spec sheet on paper — more peak hp, lighter weight, and a deeper aftermarket — but the FX140 wins the things you actually feel on a long ride: oil cooling that holds temperature, push-button starting when you're tired, hydraulic discs, and a US warranty you can call. Pick the priority that matches how you ride.
Which 140cc Pit Bike Should You Buy?
Buy the SSR SR140TR if peak horsepower and low weight top your list, or if you already live in the SSR aftermarket and want the easiest path to parts and mods. Buy the FX140 if you'd rather have oil cooling, electric start, hydraulic brakes at both ends, a ready-to-ride kit in the box, and a US-based warranty with direct support.

Which is faster, the FX140 or the SSR SR140TR?
The FX140 has a stated top speed of 65 mph. SSR does not publish a top speed for the SR140TR, so a direct top-speed comparison isn't possible from official figures. On peak horsepower, SSR lists 12 hp at 8,500 rpm versus the FX140's roughly 8.7 hp at 7,000 rpm.
Does the SSR SR140TR have electric start?
No. Per SSR's listing, the SR140TR is kick-start only. The FX140 has electric start with a kick lever as backup, so you can thumb a button to fire it up and still have the kickstarter if you ever need it.
Is oil cooling actually better than air/oil cooling?
For heat management it helps. Oil cooling circulates oil to pull heat away from the engine more consistently, which matters most on hot days and longer sessions. SSR lists the SR140TR as air/oil-cooled; the FX140 is oil-cooled.
Which pit bike is lighter?
The SSR SR140TR is lighter. SSR lists it at 157 lb, while the FX140 has a net weight of 174 lb. If low weight is a priority for you, the SR140TR wins that measure.
What kind of warranty and support does the FX140 come with?
The FX140 comes with a 1-year limited warranty and US-based direct parts support, so you can reach the seller directly for parts and help. SSR support runs through its dealer network, so the experience can vary by dealer.
