Biltwell Bonanza Spectrum LE Helmet

Same 21st century comfort and ‘70s certified styling as their popular open-face Bonanza helmet, now in an even tastier range of colors and flavors. The LE stands for Limited Edition, because that’s what each of these 3/4 DOT-compliant helmets is- a retro-inspired skid lid with custom paint schemes and graphics in small quantities for fashion-backward bikers. The Bonanza's interior features a custom-shaped EPS safety shell and a hand-stitched removable liner with moisture wicking brushed Lycra panels and open-cell foam padding for breathability and comfort. Its injection-molded ABS outer shell features hand-laid graphics and paint beneath a rugged clear topcoat. It's comfortable neck strap features plated steel D-rings and a snap strap end retainer with Biltwell anvil branding. The Biltwell Bubble Shield is also available separately.


  • Limited Edition graphic styles in two colorways available
  • Expanded polystyrene inner shell
  • Removable liner with contrasting diamond-stitched quilted open-cell foam padding
  • Meets DOT safety standards
  • D-ring neck strap with adjustment strap end retainer
  • Chrome accent edging

LOVE This Helmet!! VERY impressed with the Biltwell Bonanza Helmet. I have a number of Bell Custom 500's, but I think this is my new favorite. For me, the fit and comfort of the Biltwell are superior to the Bell... I normally fall right between a Medium and Large size-wise, sometimes making a final selection difficult. The Bonanza in Medium fits me spot-on, leading me to say, as other reviewers have, that this helmet fits just slightly large. Happily, there is also plenty of room for glasses to be worn comfortably without pinching. I'd also say that the finish on this helmet is exceptional for the price - I purchased the Red, White, & Blue version, and it is beautifully made. An added bonus, and an additional advantage over the Bell, is the removable and easily-replaced liner. Overall, I'm thrilled with this great helmet, and will certainly purchase another from Revzilla in the future! February 9, 2015

As advertised Great for the price............................................................ December 15, 2014
A great purchase! Love this helmet. Probably the most comfortable and stylish helmet that I've owned in 25 years of riding. Great bang for the buck with this one. Will definitely buy another Biltwell helmet in the future. Thanks for the great service and lightening fast shipment, Revzilla! November 17, 2014
This helmet is awesome! I love the helmet! It's so comfortable for my round head. I added the rainbow Bubble Shield, and they look amazing together. Totally fun - even the Biltwell guys loved my photo on Instagram. Thanks!! Polka August 25, 2014
Vintage Look for Adventure Riding I don't usually take the time to write reviews, but this Helmet has got me wanting to share my first ride with everyone! I've had a true vintage 3/4 helmet for a few years. I switch back and forth between that and the Full Face Dual Sport helmet on my DR650. The "Old" helmet fit terribly, it was too big, lifted up when I was cruising on the highway, and pulled all the hairs out of my beard with it's weird clasp. Needless to say, I was in the market for a "New" helmet. My wife requires me to wear a DOT helmet, so after looking through all the Biltwell's, I decided to go with the Bonanza Racer, with the Off-White/White and Gold stripe. It's amazing! The Helmet is just outside of my field of vision, so I can see everything front, and sides. It's cool, like I'm not wearing one. And the weight, it's super light. Before, I felt like I was straining into the wind. I was surprised at how much sound was blocked out with the ear/cheek pads. It's muffled. No need for earplugs on a long ride. I did notice the shape of the helmet will require me to wear a scarf this winter. I could feel a breeze on the back of my neck. Great for the Summer, this winter when it's 40 degrees in the Midwest, scarves are a requirement anyway. The only thing I have to say about the fit, is that I must have really large ears. When I put it on, the interior padding pushes the top of my ear down. Even when I reach a finger in there to straighten it out, the liner moves around and feels strange. I'll get used to it, I'm sure. I hate reading reviews about how Helmets match the bike, just look cool, whatever. If you're looking at a Biltwell, you already know what's cool and what isn't. Just get one of these, go out and ride, and have a good time. I'd recommend this Helmet to everyone, including my good Buddy, Austin Vince! Cheers September 21, 2014
Best 3/4 I've ever had I'm beyond happy with the fit of this helmet. I've got a giant head, and the XXL fits perfectly. I got the white/silver, and it's awesome. I ride a Triumph Bonneville T100... July 18, 2014

Juan Pablo M: We'll this is a very good looking helmet (retro style) but I only use it for city riding, but not for regular trips or long distances take into consideration that all open face helmets are very uncomfortable (wind, rain, Mosquitos, etc. it hurts) as safety goes full face, is always the way to go...

Not to confuse you but if it's your first bike and/or helmet always think on safety and don't go cheep!!!!! On my case I have several bikes and helmets, in this case I really have it just for the looks. But my every day helmet is a full face.

hope this helps

Gregory C: If you intend to use that Ducati the way it was designed to be used, get an Arai or Shoei full face. Biltwells are fashion helmets designed for not much more than a lowspeed impacts.
