The Honda Forza 750 (RH11) represents a significant engineering milestone: it is the first flagship maxi-scooter to successfully bridge the gap between grand-touring luxury and the mechanical architecture of a mid-sized motorcycle. Unlike traditional scooters using a CVT, the Forza 750 utilizes a high-torque 745cc parallel-twin mated to a 6-speed Dual Clutch Transmission (DCT), a configuration derived directly from the Africa Twin and NC750X platforms.
Engineering Analysis: The Euro 5 RH11 Platform
The RH11 generation introduced in 2021 was engineered to meet stringent Euro 5 emissions standards without sacrificing the low-to-mid range grunt the NC-series engine is known for. The inclusion of Throttle By Wire (TBW) allowed Honda to implement four riding modes and a refined Honda Selectable Torque Control (HSTC) system. The chassis geometry, featuring a 17-inch front wheel, provides a level of high-speed stability and turn-in precision that is virtually unmatched in the maxi-scooter segment.
Maintenance Guide & Fluid Specifications
Maintaining the Forza 750 requires precision, particularly regarding the DCT system. Using the correct oil is non-negotiable for clutch longevity and shift quality.
- Engine Lubrication: Use only SAE 10W-30 oil conforming to JASO T 903 standard MA. While a standard oil change requires 3.2 liters, a filter replacement increases this to 3.4 liters. If the engine is completely disassembled, the dry capacity is 4.0 liters.
- Ignition System: The RH11 utilizes high-performance NGK IFR6G-11K Iridium plugs. These are designed for long service intervals but should be inspected for fouling to maintain Euro 5 fuel efficiency levels.
- Tires and Handling: To maintain the intended ‘GT’ handling characteristics, tire pressures must be strictly monitored. The front 17-inch tire requires 2.5 bar (36 psi), while the 15-inch rear requires 2.8 bar (41 psi).
Electrical and Battery
The Forza 750 is equipped with a high-drain electrical system due to the Smart Key system, LED lighting, and the TFT display. The YTZ14S battery is the specified power source. If the vehicle is stored for more than two weeks, a dedicated lithium-compatible or AGM tender is recommended to prevent ‘parasitic drain’ from the immobilizer system.
Frequently Asked Questions
What is the oil change interval for the Forza 750?
Honda recommends an oil and filter change every 12,000 km (approx. 8,000 miles) or 12 months, whichever comes first. However, frequent DCT usage in urban environments may warrant earlier changes.
Can I use 10W-40 oil?
While 10W-40 may be used in emergency situations, Honda specifically optimizes the DCT solenoid response for 10W-30. Using heavier weights can result in sluggish gear changes in cold temperatures.
Why does the Forza 750 use a 15-inch rear wheel?
The 15-inch rear wheel allows for increased under-seat storage capacity while the 17-inch front wheel maintains motorcycle-like steering geometry and gyroscopic stability at high speeds.
