Exceptional service! Great pricing!

I saw one of TR's reels on Facebook Marketplace with a smoking deal on the 2024 Alpinestars Tech 7s. I called TR, left a message & he called me back shortly after. He told me the last size 12s were sold. I thought to myself "Oh great, another Facebook Marketplace scam" until TR remedied by working with me on another option that worked perfectly. I thought "who does this type of customer service anymore?" That was Monday. The boots arrive today (Thursday), just in time for a weekend ride! Thanks TR!

Shoei RF-1400 Helmet - Matte Black - Size Large - USED / OPEN BOX

Best All Round ADV boots

I’ve been riding with the Gaerne G Dakar Gore-Tex boots for a few weeks now, and they’ve exceeded all expectations. The build quality is phenomenal—solid protection without feeling overly bulky. The Gore-Tex lining does exactly what it promises: my feet stayed dry through heavy rain and shallow water crossings, yet still felt breathable in warmer conditions. The hinge system gives great ankle mobility, making them comfortable both on and off the bike. Traction on the sole is excellent, whether I’m on pavement or loose terrain. Highly recommend for adventure riders who want durability, comfort, and all-weather performance.

Shoutout to the team at Motor Psycho Sports—truly top-notch service from start to finish. They were knowledgeable, patient, and made sure I was getting the right gear for my riding style. Their communication was clear and prompt, and they went above and beyond to help me with sizing and fit for the Gaerne boots. It’s rare to find a shop that combines expertise with this level of customer care. I’ll definitely be coming back for future gear!

Gaerne SG12s

Stunning boots, these things definitely will turn some heads. First time trying them on, I immediately felt the difference in ankle support and quality. My first ride with them went perfect (comfort and feel of the bike) and they cleaned up easily. I’m very happy with my purchase and the customer support from Motor Psycho Sport…they had the best price for these brand new by a lot.

Alpinestars Smx S Waterproof Boots

Best boots out there

Been using SG12s for the past 5 years. before was using the Alpinestars tech 7s. These have SO much more protection. Maybe next time I'll try the SG22s but for the great price here I'm very happy with these.

HJC RPHA 91 - Combust MC-1SF Helmet Review & Motor Psycho Sports Shopping Experience

I recently purchased the HJC RPHA 91 - Combust MC-1SF from Motor Psycho Sports, and I couldn’t be happier with both the helmet and the shopping experience.

Helmet Review: HJC RPHA 91 - Combust MC-1SF

The HJC RPHA 91 is a premium modular helmet designed for touring and long rides. Here’s what stood out to me:

✅ Comfort & Fit – The helmet fits snugly but remains comfortable even on extended rides. The interior liner is plush and moisture-wicking, keeping me cool and dry.

✅ Noise Reduction – One of the best aspects of the RPHA 91 is its exceptional noise reduction. Even at highway speeds, wind noise is minimal, making for a quieter and more enjoyable ride.

✅ Ventilation – The airflow system is well-designed, keeping fresh air circulating without excessive noise or turbulence.

✅ Modular Convenience – The flip-up chin bar operates smoothly with a secure locking mechanism, making it easy to switch between full-face and open-face configurations.

✅ Safety & Build Quality – The helmet feels incredibly sturdy, with HJC’s Premium Integrated Matrix EVO (P.I.M. EVO) shell providing excellent impact protection while keeping it lightweight. It’s also DOT & ECE certified for added peace of mind.

✅ Sun Visor & Visor Clarity – The built-in drop-down sun visor is a game-changer, offering great visibility without needing separate sunglasses. The anti-fog and anti-scratch coatings ensure clarity in different weather conditions.

Shopping Experience: Motor Psycho Sports

I purchased this helmet from Motor Psycho Sports, and their service was top-notch.

⭐ Great Selection – They carry a fantastic range of helmets, gear, and accessories, making it easy to find exactly what I needed.

⭐ Customer Satisfaction – Their team was responsive and helpful, answering my questions before purchase and ensuring I picked the right size.

⭐ Fast Shipping & Handling – My helmet arrived quickly and was packaged securely to prevent any damage. They clearly take care in their shipping process.

Final Verdict

The HJC RPHA 91 - Combust MC-1SF is an outstanding modular helmet that delivers comfort, safety, and versatility for riders who demand the best. Coupled with the excellent service from Motor Psycho Sports, this was an all-around great purchase. Highly recommend both the helmet and the retailer!

⭐ Rating: 5/5 ⭐
