Key Features
Highly flexible Nucleon Plasma Back Protector: Constructed from viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies.
Lightweight and highly ventilated, this protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions.
Lightweight and ultra-vented chest armour: The chest outer shell ™s design is based on geodesic polyhedrons, and like a geodesic dome, less material is needed to achieve the desired structural strength and imposed load performance when compared to flat or unfaceted surfaces.
This results in a protector where the whole is greater than the sum of all its parts, making the new A-4 Plasma Chest Protector supremely light-weight and ventilated.
The over-injected flexible side wings of the chest protector perfectly follow the body ™s contours for superior comfort and freedom of movement.
Optional Race kit: Engineered to be compatible with the Nucleon Plasma Extended Roost Coverage kit which includes Upper and Lower Chest Extensions, and an additional Y-Strap System to use the A-4 Chest without the back protector.
Rib and shoulder coverage: A-4 Plasma Chest Protector features highly perforated, adjustable and detachable rib and shoulder padding for additional coverage against roost and impact.
Construction
- Equipped with adjustable shoulder and side straps for an optimised performance fit.
- Removable soft tactile thermoformed shoulder padding for enhanced rider comfort.
- The lining on the back protector offers a soft tactile feeling against the skin while maintaining the integral structure of the protectors and reducing the risk of any material tearing.
- The lining is ribbed for superior airflow while also reducing the amount of material that is in contact with the skin.
- The perforated 3D mesh chassis also offers additional protection against tire roost.
- Bionic Neck Support compatibility via the BNS shoulder pull tabs.
- USDA certified bio-based eco-friendly and sustainable impact absorbing material.

Purchased my first 2T here, a Beta 200. It was strange, I’d tell friends where I was buying it and they all told me, “oh Chas will look after you.” And look after me he did! DVLA caused some delays and Chas took care of it all and helped me throughout. My next bike will also be bought from Chas! I’d have no hesitation in recommending John Lee & Sons.

I reached out regarding the Beta Xtrainer 300. I am currently researching the market to see what options I have for an enduro/trail bike. I am fairly short so before putting this bike on my shortlist, I wanted to check the seat height in person and see if I could actually reach the ground with one or both feet. They replied straightaway, and they even offered to unbox a brand new bike and put it together for me to check. I went to the shop on Saturday and I must say that they were very helpful. Went to the garage on the back and brought out an Xtrainer for me to check. Also explained what options I have in terms of lowering the bike etc… I didn’t get the name of the young guy that helped me, but if you happen to read this, thank you! I have dealt with other big brand dealers (even “premium” like MV Agusta, Ducati…), and this has been the best experience. Very friendly and approachable. Even knowing that I just wanted to check the bike out and had no intention of buying yet. Also, they seem to be a family run business which for me is a massive plus. I will definitely buy the bike here if I end up going for the Beta. Thank you!
