Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 Youth is optimized for MX, Enduro and Off-road use, and features a whole raft of technologies and innovations taken from Alpinestars range of adult helmets to deliver the optimal blend of performance, protection and comfort. This lightweight 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. Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three sizes (Youth Small, Youth Medium and Youth Large. The SM3 Youth weighs 1060g (ECE) and 1170g (DOT). Separate versions of the shells for DOT and ECE requirements; the DOT certified version of the helmet’s inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts. The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as genuine spare parts in different thicknesses. Youth Medium and Youth Large sizes share the same EPS size, which allows riders with an YM size to initially buy an YM helmet and then configure it to a Youth Large size as they grow via the crown and cheek pad spare parts. The Youth Small has a smaller EPS size and can be customized only via the cheek pads. Alpinestars extensive research has shown that the kids that wear a YS size are very small, typically 3 to 4 years old, and therefore they require a dedicated helmet fit. Multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping reduce overall weight. The inner and outer surfaces are engineered to minimize the effects of oblique impacts. Alpinestars patented low friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s own low friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts. Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider’s neck during an impact. Comfort liner is constructed using recycled materials for a lower carbon footprint.

Customer video review of 70/100-19 E-Moto Motorcycle Inner Tube (2.75/3.00-19) for Surron, E-Ride PRO & Talaria

The tube popped on first inflation; not sure if it arrived with integrity issue or is operational error. Would like a replacement tube shipped.

70/100-19 E-Moto Motorcycle Inner Tube (2.75/3.00-19) for Surron, E-Ride PRO & Talaria

Store owner replied: Hey Luke, sorry to hear that. Tubes are shipped brand new, and unless there was visible shipping damage, what you're describing sounds a lot like a pinch flat during installation. We've all done it. Motorcycle tubes can get pinched between the tire and rim during mounting, and sometimes they don't show themselves until inflation. For the next install, we recommend using a little baby powder or soapy water and taking extra care with the tire spoons. That goes a long way toward preventing pinches.

Customer photo review of MAXIMA MTL-R Fluid Light Racing 80w Liter

I ordered 2 different items. The first item which was oil delivered within 2 days. Very fast. I was pleased with this. I was hoping the handlebars I ordered would also arrive. Live the Gnar said it was shipping seperate. As of now its been 7days since I placed the order. I reached out via email. Someone responded saying they would look at order and tracking. Its been 2 days and no one has responded. I bought the handlebars as a gift for someone. Definitely would've thought I would've received them or at least received a response from Live the Gnar. This sucks. Either way, I'll just order from another vendor from now on.

Tony Y. 1/5 Verified

MAXIMA MTL-R Fluid Light Racing 80w Liter

Store owner replied: Hey Tony, glad the oil got there quick. The handlebars shipped separately, which is pretty common when different products come from different warehouses. Oil also has to be packaged separately for shipping reasons. The tracking for the bars was emailed directly to you, and they were already on the way when this review was posted. We totally understand being excited for a gift to arrive, but a one-star review feels a little harsh for an order that was shipped and in transit. Either way, we appreciate the business and hope the bars worked out once they landed.

Customer photo review of Motoz Tractionator Desert H/T Hard Terrain Tube Type Front & Rear Tires

Live the gnar has amazing prices, selection, and fast shipping! I wanted some gnarly tires to ride more serious off-road with my big Super Tenere, they had the exact killer Motoz Tractionator Desert HTs I was after. These things look like some serious SxS tires 😆 Can't wait for the snow to melt and get them on some trails! 🤙
