For owners of the iconic CB133 motorcycle—a trusted workhorse for daily commutes, long-distance rides, and light off-road adventures—and 133cc utility tricycles used for cargo transport and rural mobility, investing in high-quality, performance-driven engine parts is non-negotiable. The CB133 Piston emerges as a purpose-engineered solution, crafted to meet the unique demands of 133cc engines where power, durability, and perfect fit are critical. As the central component of the combustion chamber, this Piston works in seamless harmony with Piston ring sets to seal the cylinder, transfer combustion power to the crankshaft, and maintain optimal compression across diverse operating conditions. Whether you’re repairing a CB133 with authentic motorcycle parts, upgrading a 133cc utility tricycle with robust tricycle parts, or maintaining small-engine machinery that requires consistent performance, the CB133 Piston delivers the reliability and versatility that 133cc vehicle users trust.
CYL DIA (Cylinder Diameter): 58.5 mm – This precision-machined diameter is tailor-made for 133cc engines, ensuring a tight, leak-free fit within the cylinder bore to preserve peak compression. The 58.5mm size optimizes combustion pressure, delivering robust low-to-mid-range torque ideal for accelerating from stops (on motorcycles) or hauling moderate cargo (on tricycles) while balancing fuel efficiency for extended rides—perfect for both daily commuters and commercial operators.
TOTAL HIGH (Total Height): 38 mm – The balanced total height strikes a perfect compromise between structural integrity and installation flexibility. It fits seamlessly into the CB133’s engine bay and most 133cc engine setups without modifications, ensuring compatibility with existing motorcycle parts or tricycle parts while maintaining the vehicle’s agile handling and compact profile.
COMP DIST (Compression Distance): 21 mm – This carefully calculated distance optimizes the engine’s compression ratio for balanced performance, striking a perfect blend of power and fuel efficiency. It ensures efficient combustion in 133cc setups, generating enough power to handle steep hills or full cargo loads without straining the engine—essential for users who demand versatility from their vehicles.
Piston Ring Dimensions: 0.80.82.0 mm – The (included) Piston ring set features ultra-thin 0.8mm primary/secondary compression rings and a 2.0mm oil control ring. This design reduces friction at high RPMs while enhancing sealing performance and oil control—critical for 133cc engines that operate across diverse conditions, from stop-and-go city traffic to steady highway cruising. The 2.0mm oil control ring adds durability, making it ideal for heavy-use scenarios.
PIN DIA (Piston Pin Diameter): 14 mm – The 14mm piston pin ensures a secure, low-friction connection to the connecting rod, balancing strength and weight to handle the cyclic stresses of 133cc combustion. Its precise diameter guarantees smooth movement, extending the piston’s service life in both daily and heavy-use scenarios.
PIN LENGTH: 42 mm – This extended length provides stable, even support for the connecting rod, distributing pressure across the piston’s wrist pin boss to prevent lateral movement and premature wear. It ensures alignment across all operating speeds, safeguarding both the piston and rod from damage during aggressive acceleration or prolonged operation.
High-Strength Forged Aluminum Alloy – Constructed from forged 2024-T3 aluminum alloy, the CB133 Piston offers exceptional tensile strength and heat resistance (up to 360°C). Forging eliminates internal defects, creating a dense structure that can withstand the higher pressure and temperature of 133cc combustion—ideal for tricycles hauling 120+ kg loads or motorcycles used for long-distance tours.
CNC Precision Machining – Every CB133 Piston undergoes rigorous CNC machining, with tolerances within 0.001mm. This ensures a perfect fit with the cylinder bore and Piston ring grooves, eliminating leaks and maintaining consistent compression. Unlike generic pistons that require tedious adjustments, this part is ready for installation out of the box, saving time for mechanics and DIY enthusiasts.
Low-Friction Skirt Coating – The piston’s skirt features a specialized diamond-like carbon (DLC) coating, reducing friction between the piston and cylinder wall by up to 45%. This coating minimizes wear, improves heat dissipation, and extends the piston’s lifespan by up to 60% compared to uncoated alternatives—ideal for vehicles that log high annual mileage or operate in harsh conditions.
Reinforced Crown & Wrist Pin Boss – The piston crown is reinforced with additional material to handle detonation and heat, while the wrist pin boss features a thickened design with internal ribs for extra strength. These enhancements make the CB133 Piston uniquely suited for heavy-duty applications, such as commercial tricycle delivery or off-road riding.
CB133 Motorcycle Compatibility – It’s a direct replacement for all CB133 variants, including base models, upgraded editions, and custom builds. Whether you’re repairing a well-used CB133 that’s logged thousands of kilometers or restoring an older model, the CB133 Piston integrates seamlessly with the bike’s original motorcycle parts to restore factory-level performance.
133cc Tricycle Compatibility – For 133cc utility tricycles used for small-scale commercial transport (e.g., urban food delivery, rural errand-running, or light farm work), the CB133 Piston is a reliable upgrade. It works with standard tricycle engine setups, pairing with tricycle parts to deliver the durability needed for daily heavy loads and rough road conditions.
133cc Small-Engine Compatibility – Beyond two and three-wheelers, the CB133 Piston fits 133cc small-engine machinery (e.g., medium-duty generators, small agricultural pumps) that requires consistent performance, expanding its utility across engine parts applications.
Enhanced Torque & Responsiveness – The precision 58.5mm cylinder diameter and optimized 21mm compression distance ensure maximum compression, delivering a noticeable boost in low-end torque (up to 10.8 N·m). This makes CB133 motorcycles more responsive in traffic and tricycles better equipped to handle hills or cargo without losing power.
Improved Fuel Efficiency – By reducing friction with the ultra-thin Piston ring set and DLC coating, the CB133 Piston cuts fuel waste by up to 14% compared to worn or generic pistons. For daily commuters logging 110km weekly, this translates to monthly fuel savings of $20–$27— a significant benefit for budget-conscious users.
Reliable Operation in Harsh Conditions – The high-strength materials and heat-resistant design prevent engine overheating and piston failure in extreme conditions, such as riding in 40°C+ temperatures or hauling cargo on unpaved roads. Users report consistent performance even after hours of continuous operation, reducing downtime and repair costs.
Reduced Maintenance Frequency – The anti-wear coating and reinforced design minimize wear on the piston, cylinder walls, and connecting rod, extending the engine’s overall lifespan. Many users report their engines running reliably for an additional 35,000km after installing the CB133 Piston—saving time and money on frequent repairs.
CB133-Specific Engineering – Unlike generic pistons designed for “one-size-fits-all” small engines, it’s engineered exclusively to match the CB133’s engine specifications. This ensures perfect fit, optimal compression, and performance that aligns with the vehicle’s original design.
Dual-Vehicle Versatility – It works seamlessly with both motorcycle parts and tricycle parts, making it a versatile solution for users who own multiple 133cc vehicles or small repair shops serving diverse clients.
Balanced Performance & Durability – It’s built to deliver both power and longevity, catering to the diverse needs of 133cc vehicle users—from daily commuters seeking fuel savings to commercial operators needing reliable torque and durability.
OEM-Grade Quality – The CB133 Piston meets or exceeds original equipment manufacturer (OEM) standards for the CB133, ensuring it’s a direct, safe replacement for factory parts. Unlike cheap imports, it’s tested for performance and durability before leaving the facility.
