MX26 Collection
The S-M7 Helmet is engineered for off-road racing, and is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight helmet, while its supremely aerodynamic composite shell delivers exceptional impact protection. As well as Alpinestars patented A-Head Fitment and Visor Detaching Systems, the S-M7 is equipped with innovative PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area.
Features:
- Energy-Deflecting Design: The helmet’s curved shell is engineered to reduce friction and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash.
- PLASMA Inside: Alpinestars patented PLASMA technology is strategically-integrated into the S-M7’s side pads for high performance shock absorption in a critical area, significantly reducing the risk of injuries.
- A-Head Technology: Alpinestars patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head for an optimized performance fit.
- Patented Visor Release: The S-M7’s patented Visor Release System is designed to detach during a crash, reducing the risk of helmet damage or rotational injury.
- The S-M7’s visor is engineered to automatically detach from the shell when it is subjected to an impact energy greater than 15 Joules for optimum impact protection, regardless of the direction.
- Shell Sizing for Optimal Fit: The S-M7 shell sizing solution ensures each helmet fit size delivers the most anatomical solution for the wide variety of fit needs worldwide, providing 3 different helmet shell sizes and 6 consumer sizes from XS to XXL to ensure riders have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact.
- Hydration System Ready: The helmet incorporates integrated channels on both sides to accommodate a hydration system.
Construction
- Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head.
- Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum ventilation.
- Eject Removal System Ready: the helmet is designed to accomodate the installation of an eject removal system, which includes a removable insert on top of the EPS.
- Removable Lining: With a 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness.
- The S-M7’s fit can be further customized via the Alpinestars genuine replacement cheek pads, which are available in all thicknesses, and are exchangeable between all shell sizes.
- Lightweight: ECE 1280g and DOT 1340g for a size medium.
- The S-M7 is available in 2 versions: ECE2206 and DOT homologation standards.
Protection
- The result of the unique shell lay-up process employed in the S-M7 construction results in extremely effective impact protection. The S-M7 returning linear and oblique impact performance significantly exceeds current helmet regulation standard limits.
- Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled to specially-developed surface in the comfort liner. This Alpinestars Patented Specific Coating technology reduces rotational acceleration transmitted to the rider’s head: the S-M7 Helmet exceeds the new ECE 22.06 Peak Rotational Acceleration standard by 76%.
- Profiled chin bar for proven impact protection.

If we care about racism and white privilege, what should we do?
Format: Kindle
One hundred and fifty-two years ago, slavery ended in the United States. And yet the tentacles of that time touch lives every day, all these years later.
What can be done to make things better? Michael Eric Dyson, a sociology professor at Georgetown University, and an ordained Baptist minister, suggests that white people who care about the lives of black people should make individual reparations. In his book, Tears We Cannot Stop …A Sermon to White America, Dyson says, “{Black people} built a legacy of excellence and struggle and pride amidst one of the most vicious assaults on humanity in recorded history. That assault may have started with slavery, but it didn’t end there. The legacy of that assault, its lingering and lethal effect, continues to this day. It flares in broken homes and blighted communities, in low wages and social chaos, in self-destruction and self-hate too. But so much of what ails us—black people. That is—is tied up with what ails you—white folk, that is. We are tied together in what Martin Luther King Jr. called a single garment of destiny. Yet sewed into that garment are pockets of misery and suffering that seem to be filled with a disproportionate number of black people.”
The book, unlike Dyson’s other scholarly works, takes the form of a worship service, and uses the concept of an extended sermon, or jeremiad, to lead the reader through confession, repentence, and redemption “through the long night of despair to the bright day of hope.” In Dysons’s view, “whiteness is a problem to be struggled with,” and his book is of inestimable value in grappling with the struggle.
The book speaks at length of police brutality against black people, and fervently tries to create empathy in white readers. It includes an extraordinary bibliography of books which give insight and voice to black history, oppression, pain, achievement, and lives.
And it speaks of reparations, and our responsibility as white beneficiaries of an unequal system, to take concrete actions to right the wrong, the change our country and the lives of our black sisters and brothers and their children.
Dyson is imaginative, and has many suggestions for how an individual or group “I.R.A.”—an Individual Reparations Account. We could buy books for black college students, overpay our black accountant or hairdresser, pay the black person who cuts our grass double the amount on the bill, give to the United Negro College Fund, and more. He suggests that faith groups consider giving 10% of their revenues to a church I.R.A. In an interview in the New York Times Magazine, Dyson says, “If the sermon ain’t making you a little bit uncomfortable, it ain’t effective. Look, if it doesn’t cost you anything, you’re not really engaging in change: you’re engaging in convenience. I’m asking you to do stuff you wouldn’t ordinarily do. I’m asking you to think more seriously and strategically about why you possess and what you possess…..you ain’t got to ask the government, you don’t have to ask your local politician—this is what you, an individual, conscientious, ‘woke’ citizen can do.
I have read many—though surely not all—of the books Dyson recommends. I have grappled with white privilege as a mother of black children, a fighter against apartheid, a civil rights activist, a human being. I have never read anything which more cogently offers “woke whites” a path to being a part of the change. I urge you to read Tears We Cannot Stop …A Sermon to White America, and to take your place in the pantheon of people who help this country grow beyond its racist past.

Powerful and especially so read aloud by the author.
Format: Audio CD
Hearing this powerful book read by Dr Tyson made it doubly understandable and enlightening. I needed to hear the experience, hurt and anger expressed so incredibly honestly and with the power of his emotion. I saw the CDs here at a reasonable price and I am so much more aware hearing rather than reading this book. Dr Tyson teaches powerful historic and current systemic racial experience such as every white person will do well to encounter. If you want to learn more than you already know, listen to these CDs on Black experience from Dr Tyson. Could be disturbing to anyone who does not want to learn the truth he teaches. It’s so packed with truth I will listen to it more than once more. Thank you, Dr Tyson.

brilliant, painful
Format: Hardcover
Timely, provocative, brilliant, painful, and, ultimately, a very necessary step toward authentic national healing and transformation. As a white, long-time fellow traveler, I am so grateful that Dr. Dyson has answered his calling to lead us toward redemptive justice with truth, decency and love--albeit, at times, necessary tough love. I am in my third read already and learning more and more each time.
Dyson's sermon serves as an exceptional read for believer and non-believer alike as it offers a framework and lexicon for us to engage with one another as we work our way through ongoing racially turbulent and polarized times. I am not a critic by trade so I will leave the professional analysis to the experts. I am a K-12 educator and seeker of social justice. I found this work both accessible and challenging in the best of ways. In my daily work, the evidence of the invention of whiteness, white innocence and white fragility and their pernicious impacts are ubiquitously abundant such that Dyson’s claims simply cannot be denied.
Dyson’s sermon is not always a comfortable read. That’s the point. It is a workout for the soul and psyche that results in the growing pains necessary for personal and collective liberation.
Thank you, Rev. Dr. Michael Eric Dyson, for opening your head and heart so broadly and deeply there is room enough for all of us in this racial healing process. The writing of this book is the ultimate act of truth and forgiveness. You have entrusted us with your most profound insights, personal experiences, and extend a vulnerability that humbles and arrests me. As you shared in a recent interview, "your trust in us grows out of forgiveness and the demand for truth for which is stands on, and the love it seeks to extend". Amen! I am in!
