Malossi vs NCY Performance Parts: Which Is Right for Your Scooter?
When it comes to upgrading your scooter's performance, two brands consistently rise to the top of the conversation: Malossi and NCY. Both are well respected in the scooter community, both are stocked at Scooterworks USA, and both can transform a stock scooter into something significantly more exciting. But they are not the same, and choosing between them is not always straightforward.
This guide breaks down the key differences between Malossi and NCY performance parts, compares them category by category, and helps you figure out which brand makes more sense for your specific scooter, engine, and riding goals.
Who Makes Malossi and Who Makes NCY?
Malossi is an Italian manufacturer with roots going back to 1950. The company has spent over seven decades engineering performance parts for small displacement two-wheeled vehicles, with a particular focus on European scooter platforms. Malossi parts are designed and manufactured in Italy, and the brand carries a well-earned reputation for precision engineering, quality materials, and race-proven performance. If you have ever seen a modified Genuine Stella or a tuned Buddy 170i putting out serious power, there is a good chance Malossi components are involved.
NCY is a Taiwanese manufacturer that has become one of the dominant suppliers of performance and replacement parts for GY6, QMB139, and Minarelli-based scooter engines. NCY parts are engineered to deliver meaningful performance gains at a more accessible price point than European alternatives, and the brand has developed a strong following among GY6 platform riders in particular. From transmission kits and clutches to front forks and brake calipers, NCY covers a remarkably broad range of components.
Understanding where each brand comes from helps set the right expectations. Malossi is the premium European option, purpose-built for specific platforms with exacting tolerances. NCY is the high-value performance option with broader GY6 and QMB139 compatibility and an extensive parts catalog.
Cylinders and Top End Kits
The cylinder and head are the heart of any performance build, and both brands offer strong options here.
Malossi cylinder kits are engineered for specific engine platforms and are known for tight manufacturing tolerances, high-quality materials, and significant power gains. Malossi cylinders for Minarelli and Piaggio-derived engines are particularly well regarded. If you are building a high-performance Genuine Stella or a 2-stroke Buddy 50, a Malossi cylinder kit is a benchmark choice. The trade-off is price — Malossi top end kits represent a significant investment, and they are typically platform-specific, meaning you need to match the kit precisely to your engine.
NCY offers cylinder kits for GY6 engines in popular displacement steps including 68cc for QMB139 engines (part 1100-1541) and 171cc for GY6 150 engines (part 1100-1254). NCY cylinders provide excellent heat dissipation, reduced friction, and a meaningful power increase over stock at a price point that makes them accessible to a much wider range of riders. The NCY 171cc cylinder kit paired with the Scooterworks big valve head (part 1100-1438) is one of the most popular GY6 performance combinations available.
Verdict: For GY6 platform builds, NCY cylinders offer outstanding value and proven performance. For Minarelli and Piaggio-derived 2-stroke engines, Malossi is the benchmark.
Carburetors
Malossi produces the PHBG series of flat slide carburetors, which are widely considered among the best performance carburetors available for small displacement 2-stroke scooters. The Malossi PHBG 19mm (part M1611028) delivers sharper throttle response, better fuel atomization, and improved midrange performance compared to stock CV carburetors. It is the carb of choice for 2-stroke GY6, Minarelli, and PGO 50cc performance builds.
NCY does not currently produce a direct carburetor competitor in the same class as the Malossi PHBG. For carburetor upgrades on GY6 platforms, Malossi is the clear choice.
Verdict: Malossi wins this category outright. The PHBG 19mm is the go-to performance carburetor for 2-stroke GY6 and Minarelli builds.
Transmission Components
The CVT transmission is where NCY really shines, and it is the category where the brand has built much of its reputation in the American scooter market.
NCY produces a comprehensive range of transmission upgrade components for GY6 and QMB139 engines including the NCY Super Trans Kit (part 1200-1048 for GY6, part 1200-1171 for QMB139), performance rollers in various weights, the NCY green performance clutch (part 1200-1202), and the NCY adjustable clutch (part 1200-1029). The Super Trans Kit is one of the most popular single upgrades available for GY6 scooters, combining a performance variator, rollers, and clutch components into one package that delivers noticeably better acceleration and top speed out of the box.
Malossi offers the Delta Clutch (part M5212487), which is one of the most sophisticated clutch options available for GY6 engines. The Delta Clutch features a spring preload adjustment that allows precise control over the RPM at which the clutch engages, making it a serious tool for performance tuning. It is heavier and more expensive than NCY clutch options but offers a level of adjustability that no NCY product currently matches.
Verdict: For a complete transmission upgrade package at strong value, NCY is the clear choice. For maximum clutch adjustability and performance tuning precision, the Malossi Delta Clutch is in a class of its own.
Suspension and Brakes
This is almost exclusively NCY territory, and the brand has built an impressive catalog of suspension and brake upgrades for GY6 platform scooters.
NCY produces front forks for the Genuine Buddy and RoughHouse (part 1000-1375), adjustable performance rear shocks (part 1000-1044), disc brakes in 200mm and 220mm sizes, forged brake calipers (part 1000-1311), and stainless braided brake lines (part 1100-1238). For riders who want to match their engine performance upgrades with equivalent improvements in handling and stopping power, NCY provides a one-stop solution.
Malossi does not currently produce a competing suspension or brake line for GY6 platform scooters.
Verdict: NCY wins this category by default, and the quality of their suspension and brake components is genuinely impressive.
Exhaust Systems
NCY produces performance exhaust pipes for multiple GY6 and QMB139 platforms. NCY exhausts provide a meaningful increase in midrange and top-end power while maintaining a reasonable noise level for street riding.
Malossi produces high-performance exhaust systems for Minarelli and Piaggio-derived engines including expansion chamber pipes for 2-stroke builds. Malossi exhausts are engineered specifically for their cylinder kits and are designed to work as a matched system, which is important for maximizing power on a 2-stroke engine where pipe tuning plays a critical role in the powerband.
Verdict: For GY6 4-stroke platforms, NCY exhausts are the accessible and proven choice. For 2-stroke Minarelli builds, Malossi exhaust systems are engineered to complement their cylinder kits for maximum power.
Price and Value
This is perhaps the most straightforward comparison. NCY parts are consistently less expensive than Malossi equivalents, often significantly so. The NCY Super Trans Kit, for example, delivers a substantial performance upgrade at a fraction of the cost of building a comparable Malossi transmission setup. The Malossi Delta Clutch at $180 is more than double the price of the NCY green performance clutch at $74, though it also offers adjustability that the NCY clutch cannot match.
Malossi parts command a premium because they are designed and manufactured in Italy to exacting specifications for specific engine platforms. NCY parts deliver genuine performance gains at a more accessible price point by engineering for broader platform compatibility. Neither brand is overpriced for what it delivers — they simply target different riders with different budgets and priorities.
Which Brand Is Right for You?
Here is a simple framework for making the decision:
Choose NCY if you are building on a GY6 or QMB139 platform, want the best value for your performance dollar, need suspension and brake upgrades alongside engine work, or are putting together a complete performance build on a budget. The NCY ecosystem is deep, well-supported, and proven on thousands of GY6 scooters in the US market.
Choose Malossi if you are building on a Minarelli or Piaggio-derived 2-stroke engine, want the best available carburetor for a 2-stroke performance build, are willing to invest in premium Italian engineering for maximum performance, or need the precision adjustability of the Delta Clutch for a high-output engine build.
Use both if you are building a serious GY6 performance scooter and want the best of both worlds — NCY for the transmission, suspension, and brake upgrades alongside a Malossi PHBG 19mm carburetor for the sharpest possible throttle response.
