Take your money elsewhere!

Definitely, it’s a great idea for a rider to confront a cager and escalate it into an altercation. There’s no way that would wind up terribly for the rider.

I take it you’ve never ridden a 500R then? You need to wind up the engine considerably before the power comes on, and it’s always manageable. There’s more to what makes bikes suitable for beginners than their spec sheets. Go ride them and find out for yourself.

Our advice: NEVER buy a used helmet, EVER!

From research, we know that there are 7 factors that make a helmet – any helmet – safe for its user, and for this specific user alone. (Check https://castodian.org/)

The 3 most important of these 7 factors are:
1. A helmet should be without any damage or defects
2. It should be less than 7 years old, from production date
3. The (new!) helmet should fit very tight, as it will become a bit bigger through wearing

At 1. There is NO WAY one can see and make sure whether a helmet does not have some kind of damage / crack in the inner-helmet, the impact-absorbing liner in the picture above; this goes especially for the plastic / polycarbonate helmets, as this material is highly flexible, does not (easily) break with a crash and gets back to its initial form after a crash.
However the shock-absorbing inner-helmet has sustained irrepairable damage and lost all its absorbing qualities, without this being visible, and is NOT safe!

At 2. This is a really important safety-factor as well: although (and especially with outer-shells from composite material, like e.g. fiberglass or carbon) the outer-shell will be “OK” for at least 7 to up to 10 years or longer, the inner-shell however is NOT!
This inner-shell, the part that absorbs the energy of a crash, is in 99% of all cases made of polystyrene: after 7 years, whether the helmet is being used OR NOT, this material will have lost its absorbing ability, due to the loss of the plasticisers!

(NOTE. The above thus also means that “bargains” when buying a helmet can be tricky too: these 7 years also apply to helmets on the shelf with dealers!)

At 3. If a helmet is too large (and therewith fits fairly comfortably), which is unfortunately too often the case, it either might come-off during a crash, or might shift and breaks ones collarbone or – even worse – damages neck vertebrae.
A new helmet, especially at the beginning, should fit (overly) tight, as in time it will get a bit bigger and “forms to ones head”. A used helmet had gone through this process already, with its prior user, and therefor will have a less proper fit at all times!

As a genuinly certified***, NEW and therewith in basis safe helmet can already be found from as less as $50,00, one NEVER should buy a used helmet!

(***DOT does NOT have the highest safety standard, compared to SNELL, SHARP or even ECE, but is the official and minimum certification standard for the US: there are helmets in the market that apply to several certification standards at the same time)
