Sizing and Fit
The HJC i100 offers XS through 2XL across three distinct shell sizes, ensuring optimal weight distribution and proportional aesthetics. The helmet uses an intermediate oval internal shape that comfortably fits most head shapes.
Shell Construction
The Advanced Polycarbonate shell uses three distinct sizes across the XS-2XL range. This optimizes the shell-to-head ratio for better impact energy management. The EPS liner features multiple density zones for progressive impact absorption.
Sizing Chart
For proper sizing, measure around the widest part of your head, approximately 1 cm above your ears. The size chart breaks down as follows:
| Size | Head Circumference (cm) | Hat Size | Head Circumference (inches) |
|---|---|---|---|
| XS | 54-55 | 6 3/4 – 6 7/8 | 21 1/4 – 21 5/8 |
| S | 55-56 | 6 7/8 – 7 | 21 5/8 – 22 |
| M | 57-58 | 7 1/8 – 7 1/4 | 22 1/2 – 22 7/8 |
| L | 58-59 | 7 1/4 – 7 3/8 | 22 7/8 – 23 1/4 |
| XL | 60-61 | 7 1/2 – 7 5/8 | 23 5/8 – 24 |
| 2XL | 62-63 | 7 3/4 – 7 7/8 | 24 3/8 – 24 3/4 |
Fit Considerations
The helmet includes specific features for comfort:
- Glasses-friendly grooves accommodate eyewear
- A removable chin curtain helps reduce wind noise
- Metal-on-metal chin-bar locking for secure closure
Some riders note initial tightness, particularly around pressure points. If you’re between sizes, I recommend trying the next size up. The secure fit matters most for modular helmets to prevent unwanted movement of the chin bar mechanism.
Color Options
The HJC i100 offers five solid color choices, each with distinct visibility and maintenance characteristics. To evaluate their real-world performance, I’ve tested several finishes under different lighting conditions.
Classic Solids
The White finish provides maximum visibility in daylight and low-light conditions. The standard Black and Matte Black options hide road grime better, though they require more frequent cleaning to maintain their appearance. The Semi Flat Titanium and Hyper Silver finishes strike a balance between style and practicality.
Graphic Designs
The current graphic lineup includes two options:
- Beis: Features a modern geometric pattern
- Beston: Displays a sporty racing-inspired design
Paint Quality
The clear coat application shows excellent durability. After three months of daily use, my Matte Black version hasn’t shown any significant wear marks or UV fading. The paint thickness meets ECE standards for impact resistance.
Visibility Considerations
Light-colored options like White and Hyper Silver increase rider visibility by up to 25% in low-light conditions. Dark finishes look sleek but sacrifice some visibility benefits. The limited graphic options might disappoint riders wanting more expressive designs.
HJC’s color selection focuses on practical, everyday choices rather than flashy designs. This approach lowers production costs, contributing to the helmet’s competitive price point.
Interior Comfort
The HJC i100’s interior combines practical maintenance features with rider-focused comfort elements. To evaluate its performance, I’ve tested this helmet through various weather conditions and long-distance rides.
Liner System
The multi-layer comfort liner uses moisture-wicking fabric that pulls sweat away from the skin. The material kept my head dry during my summer testing, even in 90°F heat. The antibacterial treatment has prevented odor buildup over three months of regular use.
Maintenance Features
The crown and cheek pads are easily removable, revealing a fully washable liner for convenient cleaning.. I’ve washed the liners twice, following the cold-water hand wash instructions, with no shrinkage or degradation. The pads dry completely within 24 hours.
Eyewear Integration
The glasses channels cut into the foam allow my prescription glasses to slide in without pressure points. The channels work with various frame styles, though wider sports frames might feel tight. It maintains seal integrity even with eyewear in place.
Pressure Distribution
The interior padding creates even pressure distribution across the head. The cheek pads break in after about 15 hours of wear, conforming to facial contours. Some riders with round face shapes report tight spots near the jawline.
The modular design affects interior space – there’s slightly less padding near the chin-bar pivot points. This trade-off maintains the flip-up mechanism’s smooth operation while compacting the overall profile.
How Much Does It Weight?
The HJC i100 weighs 4.4 pounds (1904 grams) in size XL, making it one of the heavier modular helmets in its class.
The increased weight comes from the ECE 22.06 certification requirements, which demand additional protective material compared to older standards.
Weight breakdown across all available sizes:
| Size | Weight (grams) | Weight (lbs) |
|---|---|---|
| XS | 1700 | 3.75 |
| SM | 1800 | 3.97 |
| MD | 1878 | 4.13 |
| LG | 1900 | 4.19 |
| XL | 1904 | 4.40 |
| 2XL | 1910 | 4.21 |
The weight distribution gradually increases across sizes, with the XL size being notably heavier than others. The helmet uses three different shell sizes to optimize weight distribution and fit.
Weight Distribution
Despite its mass, the helmet maintains a balanced weight distribution across the head. I noticed minimal neck strain during extended highway rides, though the extra weight becomes noticeable after several hours of continuous riding.
Real-World Performance
During my testing at highway speeds around 70 mph, the helmet’s weight didn’t cause excessive buffeting or head movement. The aerodynamic shell design helps offset some of the mass effects, particularly when riding behind a windscreen.
Comparative Analysis
The i100 weighs about 188 grams more than its predecessor, the i90. This puts it at the heavier end of the modular helmet spectrum, with competitors like the Shark EVO ES coming in significantly lighter at around 1600 grams.
Long-Distance Considerations
The added weight might require an adjustment period for touring riders planning extended trips. Some riders report initial neck fatigue during the first few long-distance rides. However, the balanced weight distribution helps minimize strain during normal riding conditions.
Safety Features
The HJC i100 meets both DOT and ECE 22.06 safety standards, with the European certification including more rigorous testing protocols. The helmet undergoes randomized impact testing at higher drop speeds and evaluates performance with accessories like Bluetooth units installed.
Chin Bar Protection
The rotation chin bar of the HJC i100 provides riders with the convenience of an open-face helmet when stopped, while still offering the protection of a full-face helmet when riding. Recent HJC modular helmets averaged a 92% lock retention rate in SHARP impact tests. It includes protective skirts that deploy when lifted, maintaining aerodynamic stability in both positions.
Retention System
I found the fastening system varies by market:
- US models: Double D-ring strap
- European models: Micrometric quick-release buckle
Dual Homologation
The i100 carries P/J certification, meaning it’s legally approved for use in both open and closed positions. The chin bar locking mechanism requires a deliberate action to release, preventing accidental opening during rides. A red safety tab provides additional security when the chin bar is in the rear position.
The helmet’s safety features reflect HJC’s focus on meeting the latest protection standards while maintaining the convenience of a modular design. The ECE 22.06 certification puts it ahead of many competitors who are still certified to older standards.
Ventilation System
The HJC i100 uses Advanced Channeling (ACS) ventilation inspired by MotoGP technology. During my testing in 29°C (84°F) conditions, the interior temperature matched the outside temperature exactly, demonstrating excellent thermal regulation.
Primary Airflow Components
The large chin vent offers three position settings and directs air effectively to both the mouth area and face shield. I found the controls easy to operate even with thick winter gloves. The crown vent provides two adjustment positions, channeling air through the EPS liner’s molded pathways.
Exhaust Configuration
Three rear exhaust ports actively pull warm air out of the helmet. This triple-vent design improves upon the i90’s dual exhaust setup, creating more consistent airflow throughout the helmet interior.
Real-World Performance
The ventilation mechanism performs above average compared to competitors:
- Matches the cooling efficiency of the Shark EVO ES
- Outperforms the HJC i90 by 1 degree Celsius in temperature regulation
- Maintains consistent airflow at highway speeds
The chin vent proves more effective than the crown vent in practice. While this is common in modular helmets, the integrated channels in the EPS liner help distribute incoming air across the head. It earned 4 out of 5 stars in independent testing, placing it among the better-ventilated modular helmets in its class.
Visor System
The HJ-36 face shield features Pinlock 70 anti-fog technology and UV protection. I’ve tested the visor through various weather conditions, from heavy rain to bright sunlight, to evaluate its performance thoroughly.
Main Shield Features
The quick-release ratchet mechanism allows tool-free shield changes in under 30 seconds. The shield locks securely at five different positions, with an additional city position for increased ventilation at low speeds. My testing revealed the ratchet mechanism’s consistent performance even after 100+ operations.
Anti-Fog Performance
The included Pinlock 70 insert creates a double-layer barrier that prevents fogging in temperatures from -20°C to 50°C. During cold morning rides, it maintained clear vision without condensation buildup. The insert installation takes about 5 minutes and requires no special tools.
Internal Sun Visor
The drop-down shield features:
- Three-position adjustment wheel for precise height control
- Anti-scratch and anti-fog coatings
- 95% UV protection rating
Optional Shields
HJC offers replacement shields in several tints:
- Light smoke (20% tint)
- Dark smoke (80% tint)
- Silver, blue, and gold mirror finishes
Common Issues
Some riders report the sun visor adjustment lever feels stiff initially. The mechanism loosens after about 20 operations. The main shield requires firm pressure to seal completely – I recommend checking the seal before each ride.
The visor mechanism represents a significant upgrade from the i90 model, with improved seal quality and smoother operation of the internal shield mechanism.
Noise Performance
The HJC i100 produces 101 decibels at highway speeds, performing better than its direct competitors. My testing reveals the helmet’s noise levels stay consistent across different riding positions and speeds up to 75mph.
This makes the HJC i100 one of the quietest flip up helmets on the market, providing a comfortable and enjoyable riding experience for the user. The aerodynamic design and quality construction of the helmet contributes to its impressive noise reduction capabilities, making it a top choice for riders who prioritize a quiet and peaceful ride.
Additionally, the i100’s ability to maintain low noise levels even at higher speeds sets it apart from other flip-up helmets in its class.
Wind Noise Management
The chin curtain helps reduce noise from underneath, though modular motorcycle helmets typically generate more wind noise than full-face designs. The i100’s improved sealing around the flip-up mechanism reduces noise by 3 decibels compared to the i90 model.
Safety Considerations
Wind noise under motorcycle helmets can exceed 90 dB(A) at speeds above 65 km/h. Extended exposure to these noise levels risks hearing damage after just 15 minutes of riding. The noise-reduction features include:
- Enhanced neck roll design
- Improved visor sealing
- Aerodynamic shell shaping
Hearing Protection
I strongly recommend using earplugs with this motorcycle helmet. Quality earplugs can reduce noise exposure by 15-30 dB while maintaining awareness of essential sounds like traffic and navigation systems. It accommodates foam and filtered motorcycle-specific earplugs without interfering with the internal padding.
The i100’s noise performance significantly improves over previous HJC models, though riders should still plan for appropriate hearing protection during extended rides.
