Selection Criteria
When you choose a helmet, you are balancing protection, fit, comfort, and cost. We prioritized certified safety standards and modern impact technologies like MIPS or dual-density liners, then evaluated fit systems and sizing range so you can get a snug, secure feel.
Ventilation, weight, and visor functionality were checked for real riding comfort, and price was weighed against features so you can pick the best option for your budget.
The goal was to highlight which helmet makes the most sense for different riding styles and head shapes.
You get a helmet built for off-road riding that balances protection and everyday comfort.
The V Core pairs MIPS impact mitigation with a magnetic visor designed to detach in a crash, and the multi-shell construction helps keep weight down while spreading impact forces.
Venting is generous, so you stay cooler on long runs, and the variety of shell and EPS sizes makes it easier for you to find a true-to-head fit.
Use it for weekend trail sessions, motocross practice, or any ride where you want a confidence-inspiring, purpose-built lid.

FAQ’s
How Do I Choose The Right Size And Fit?
You should measure your head around the forehead and compare that number to the manufacturer’s size chart before you buy. Pay attention to model-specific fit notes: some Speedframe variants are described as hugging the head, the V Core offers multiple shell and EPS sizes for finer tuning, and the 5050 models can run narrower. Make sure the helmet sits level on your head, the retention system is snug without pressure points, and test it with any goggles or caps you normally wear.
Are These Helmets Safe Enough For My Riding?
Most of the helmets in this roundup feature modern impact tech and meet common certifications; for example, the V Core lists DOT, ECE, and FMVSS compliance, while several models include MIPS or dual-density liners for added protection. No helmet can guarantee you’ll avoid injury, so treat certifications and impact systems as important layers of protection and replace a helmet after any significant crash or if it’s past the manufacturer’s recommended service life.
Also, check the helmet’s manufacture date when you buy to ensure you get a fresh product.
Which Model Should I Buy Based On How I Ride?
If you ride motocross or want crash-focused features, the V Core at $159.95 leans toward that use with a magnetic visor release and robust shells; for trail riders who want a close, adjustable fit, the Speedframe at $119.95 balances ventilation and feel, and the Speedframe Pro at $119.00 adds pro-level liners and a Fidlock buckle. If budget and dependable MIPS protection matter most, the Mainframe MIPS at $50.59 is a strong value, while the 5050 models suit casual riders who prefer an open-face look but should be checked for fit before you commit.
What Riders Prefer
When you’re choosing between the V Core, Speedframe, and Mainframe MIPS, you typically prioritize protection, fit, and price.
If you want crash-focused features and robust shells, you lean toward the V Core ($159.95).
For a close, ventilated trail fit, pick the Speedframe ($119.95); if value and MIPS protection are your main concerns, the Mainframe MIPS ($50.59) is the usual choice.
Wrapping It Up
If you ride motocross and want a purpose-built helmet, the V Core stands out for its crash-minded features and robust construction.
For trail riders who prize a precise, comfortable fit, the Speedframe is a strong all‑around choice, while the Speedframe Pro brings pro-tier liners and extras if you want advanced protection.
If budget and MIPS protection are your priorities, the Mainframe MIPS delivers the best value.
The 5050 models provide open-face simplicity and style, but pay close attention to sizing and fit before you buy. Use these picks to narrow your options and verify your head measurements for the best result.
