Not Happy

I wore them for the first time last Sunday and the screws came off and the right lower buckle just hanging.I paid $532.00 for these boots! Poor quality control!

Gaerne SG-22 Gore-Tex Enduro Boots - Anthracite

Amazing helmet

I will admit I was skeptical at first because the price seemed way too good to be true. But the helmet was delivered pretty quickly and packed very nicely. I really couldn’t tell it was an “open box” since everything was included and I didn’t see any scratches on the one I got. In the future, I wouldn’t hesitate to buy from this site.

As for the Shoei, I’ve been using a Ruroc Atlas 4.0 for the past few years and I will gladly admit I regretted my purchase. I should’ve spent the money on the RF1400 instead. My head isn’t getting rocked around at highway speeds on a windy day on my Harley and the wind noise is almost nonexistent compared to the Ruroc (with earplugs in). My only gripes are the liner isn’t as soft as I would’ve hoped to be for the money and replacement shields are crazy expensive.

Motor Psycho Sport

Great boot

Love the support and they’re semi comfortable to walk in. I ride AdV and adventure boots just don’t have the support but motocross boots have too much support and no traction on the bottom. These are the perfect in between in my opinion.

Alpinestars Tech 7 Enduro Drystar Boots - Black Night/Navy/Warm Gray - CLOSEOUT

SG-12 boots

So far very pleased with the SG-12 boots. They seem very supportive and protective. A little tight around the ankle but I suspect that they will break in with more use. Very happy with my purchase and the fast delivery.

Alpinestars Tech 5 Boots - Orange Fluo/Enamel Blue/Yellow Fluo - CLEARANCE

Best price & service

I purchased a pair of Gaerne boots from Motor Psycho Sport and could not be happier. They by far blew everyone out of the water on price. They shipped out fast and had them in a few days. I will be buying from them again & again.

Motor Psycho and Alpinestars Yaguara Jacket get 5 stars

I needed a Tech-Air compatible touring jacket to replace my KLIM Latitude. Turns out the Latitude that fit me to a T, did not come close to having enough room underneath to allow for the proper deployment of the new Alpinestars Tech-Air 5 Plasma air bag vest. But with its stretch and expandable construction, the Yaguara is Tech-Air compatible. Motor Psycho came through with this great jacket at a great price. Now I have the protection of the Tech-Air vest and the comfort and functionality of the waterproof and vented Yaguara. Thanks Motor Psycho.
