HELMET FEATURES

The SM5 helmet has been designed to provide MX riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort. The lightweight SM5 helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

  • An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
  • Revised the medium, large, XL, and 2XL lower shell volume to be around 3% wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44% lower than the regular-speed threshold.
  • For the new ECE 22.06 standard, the SM5 achieves a 44% better regular-speed impact rating compared to the current 33% figure, as well as a 32% better low-speed, and 31% better high-speed linear impact score than the prevailing standard.
  • Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption.
  • Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
  • Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
  • The ECE version of the SM5 helmet weighs 1,350 grams for a size medium, and 1420 grams for the ECE DOT version with shield.
  • The visor has been designed to direct air into the ports for enhanced airflow.
  • The SM5 is available in 2 versions ECE R 22.06 and ECE R 22.06/DOT.

Good Plug
Purchased this from Amazon for convenience and it arrived quickly so I was satisfied. If I order the oil and filter for mower at the same time it saves me time and I have them delivered to my door for the mower tune up.

TireJECT cannot work miracles
Size: Compact Car, Mid-size Sedan, Size: Compact Car, Mid-size Sedan
TireJECT is a surprisingly thin fluid that supposedly contains fibers that must help stop up holes. Frankly I'm still confused as to how this stuff can plug a leak, but apparently it does. Tons of reviews say so. I say apparently because the product did not completely stop a slow leak in my tire, but that's OK. I knew it likely wouldn't. I'll have to replace the tire unfortunately. I had a garage install four nearly-new tires on my car. After installing, a heavy leak was discovered in one of them. They took the tire off again and found a small tear near the rim/bead of the sidewall. Since the tear would be flat against the rim, they suggested to let them try and repair it with tire patch adhesive and lots of bead sealer. They were confident, so I went for it. It seemed to work, but it went flat a few days later. TireJECT seemed like the perfect solution to the slow leak since I wouldn't have to disturb the repair. I bought the kind without the syringe and regretted it immediately upon trying to use it. First, the valve stem removal tool broke as it loosened it. I had to buy a new tool down the road. When I went to inject, I squeezed as hard as I could but it just wouldn't flow past the TPM. It also kept leaking out of the flex joint of the nozzle. I had a huge syringe on hand, so I sucked up the rest from the bag, ziptied the hose on both ends and got the rest of the product into the tire. HURRAY! The tire pressure had fallen considerably by the next morning. BOOOoo. I contacted TireJECT, and after several emails (and long waits in between). They determined their product was not suitable for my use case. They refunded what I paid without me even asking. I really appreciated that. That said, before injecting, the tire would go flat overnight. So, TireJECT does work to a good degree. I'm half tempted to overdose the tire with another package. Give TireJECT a try! Though, be sure your situation matches their criteria. If you have a TPM, opt for the package that comes with a syringe. You will need it. Also, throw the cast pot metal, tire stem tool out and get a decent machined one before you do the repair. Thank me later.
