We know a new bar system is a purchase requiring careful consideration. Along with comfort concerns, there are often dimensional considerations specific to your own set up that must be addressed. Whether you want to confirm measurements, or are just plain curious, we thought we’d provide you with all we can to make your choices more informed. Bars are a truly three dimensional product and here you’ll find all the critical dimensions of your chosen bar. Keep in mind that clamp dimensions should be considered as well - we have included those in the clamp tech pages.
Prior to the Easton TaperWall handlebar, motorcycle bars were all made with the same, straight wall design. Since creating the process, Easton has developed and refined the cold-working of aluminum tubing that sets the standard in the industry. Our exclusive computer-engineered process allows us to create multiple tapers in the same tube, so the tube walls can be reinforced anywhere along their length with incredible precision. The result is jeweler-smooth walls that eliminate the stress points typical of other manufacturer's tubing. The unprecedented control of Easton TaperWall technology allows each tube to be precision engineered for its specific application. The resulting ultra-smooth wall transitions create multiple reinforced wall zones - effectively gusseting tubes on the inside. What this does is transfer energy down the length of the bar so shock is dampened more effectively without compromising strength.
Easton pioneered the concept of Intelligent Flex whereby durability is designed into the product without adding excess material or weight. Intelligent Flex is key to the EXP’s proven level of high performance comfort. The handlebars stay stiff and rigid to help maintain control through the fast whoop sections and rutted turns while offering enhanced damping qualities.
Proprietary Material & Manufacturing
Easton revolutionized the handlebar world in 1990 with the introduction of the 1 1/8” Taperwall handlebar which used our proprietary EA70 aluminum. The recipe for this ground breaking material was derived in our laboratories and twenty years later, Easton is the only handlebar maker with access to this remarkable premium blend of aluminum. EA70 is quite special in that even though it is a very high strength alloy, the ride quality does not suffer. EA70 is ideal for alloy handlebars because the average stress that is applied through all types of riding is far below the material’s relatively high yield strength. Additionally, its ability to absorb higher impact loads means it can withstand substantial loads without bending. EA70 is just one example of why our expertise in design, material fabrication, and thermal treatment remains unmatched in the industry.
The New Standard In Oversized
For over eighty five years Easton has been the leader in designing and engineering high performance products for some of the world’s most demanding sports. Our engineering has been proven in the AMA, NHL, MLB, and the Tour de France. Easton’s engineers have always understood a single rule - function follows form. This rule applies to the EXP handlebar system. Just as the 1 1/8” aluminum handlebar answered the needs of a sport that had evolved dramatically over the previous decade, Easton’s EXP System introduces a new phase in performance driven technology.
After countless hours of lab testing, Easton engineers found that the new 35mm (1 3/8”) handlebar offered the optimum balance of ride quality, weight and strength of all the sizes they tested; from the previous standard 7/8” bar, all the way up to a 1 1/2” bar. True to its function it just looks “right” too.
With clamps, height is often a primary consideration. Our choice of a 27mm height from the base of our clamp to the bottom of our bar (45mm b to c) on all but our universal mount was driven by our measurements of fork to bar tolerances: our bar’s center section is wider than others to help it perform better, and we also offer a 5mm offset clamp that can move the bar farther into zone directly above the forks on many bikes. With our clamp height you retain space to slide your forks up in the triple clamps while allowing for adjustment tools and fork accessory fittings too. Most stock clamps measure out lower by a few mm or more - be sure to take the height difference into consideration while selecting a bar.
Six versus Eight
In building a bar clamping system that was both strong and light, we put the material where it was needed and took it out where it wasn’t needed. Our unique ExP clamp design borrows from the factory bikes and moves away from the traditional four 8mm bolt clamp design and replaces it with an eight bolt design that uses 6mm bolts. This gives you a more secure interface between the bar and the clamp without over stressing the bolts - by distributing clamping forces over a greater area.
Top Lock™ Design
Let’s face it; no matter how much riding styles have changed over the years no one has really tried to develop a new handlebar clamp system that put the primary focus on increasing the safety of the design. Until now. Easton’s patented proprietary Top Lock Clamp system ensures the maximum amount of interface between the handlebar and the clamps while at the same time, minimizing point loading and peak stress areas - the leading cause of handlebar failure. Traditional clamp designs allow loads to place stress on the bolts, which results in bend twisting and eventually fatigue and possible failure. While working with our lab test technicians Easton engineers found that by locking down half of the top plate of the clamp before torquing the final bolts allows the clamp and handlebar interface to tighten with better load transfer.
This design also eliminates the annoying process of chasing the bolts around to try and evenly tighten them.
Because Easton designs and engineers both the clamps and the bars, the components are designed as an integrated system.
In reality the design of the clamps directly effects the performance and longevity of the handlebar. Easton’s EXP clamps were specifically designed to work with the EXP 35mm bar. By better distributing the clamping stress on the bar, Easton’s design greatly reduces the peak stress areas - reducing the chance of bar failure under load.
Mounting hardware is the critical link between your bike and your controls, so we placed as much emphasis on it as the rest of our system. Our 12.9 grade fasteners offer the best combination of strength and durability. Although we provide a comprehensive fit guide elsewhere on this site, we recognize that there are bikes and triple clamp configurations we have not been able to cover. Critical measurements and for your clamps should be verified prior to selecting the right hardware for any Easton EXP application not addressed in our fit chart.
Since we’re constantly improving and expanding our fit list, we welcome questions and concerns about your specific bike’s application any time - please .
