Street 750 twin shock upgrade

British suspension manufacturer Nitron has added to their fast growing list of Harley and custom applications with a twin shock upgrade for the Street 750, 2015 onwards. Designed as a direct replacement for the factory fitted units, the Nitron shocks offer a very wide range of both damping settings and pre-load adjustment.

The well proven Nitron gas pressurized monotube damping system is said to “offer all riders immediate improvements in both handling and ride, making the bike much more comfortable, controlled and usable under hard and prolonged conditions with shocks that are individually factory tested, tuned and set up specifically for the model concerned.
“For more confident, more demanding riders the easy to use combined compression and rebound damping adjustment offers the ability for them to tailor the suspension settings to their own requirements and ensure they are getting the full potential from the bike.”
For quick and easy ride height adjustment and set-up, both spring pre-load and overall length are both externally adjustable. Color-conscious owners can also choose between the ‘Standard’ Nitron blue colored spring, the subtler ‘classic’ titanium black spring option, or the full black body and black spring ‘Stealth’ option.
They have a 35 mm large piston monotube design, 24-click combined compression and rebound damping adjustment, are Nitrogen gas pressurized, have adjustable length and pre-load settings, hard anodized titanium finish aluminum body, 14 mm induction hardened, super polished piston rod, progressive cellular bumpstop, Teflon lined ultimate low friction spherical bearings and ‘FLEXaLIGHT’ coated silicone steel springs.
All Nitron shocks are fully serviceable, rebuildable and backed up by a worldwide service center network.

Design Engineering Inc.

DEI helps cool off the red hot Slingshot

Avon Lake, Ohio based thermal barrier and sound control specialist Design Engineering is now offering a custom-cut, 11-piece heat management kit for the Polaris Slingshot.

With its compact design and four-cylinder engine, the muffler, catalytic converter and exhaust manifold of the Slingshot all reside in close proximity to one another on the right side of the vehicle. This concentration of heat easily transfers into the passenger area – potentially cooking the floor and driver.
After some R&D work with a range of thermal and acoustic materials, DEI has developed a kit that is said to “address all of the heat and noise issues,” according to DEI Powersports VP of Marketing and Sales Tom Miller.    
The kit includes a double walled main heat shield, a single walled floorpan heat shield, nine additional pieces to cover the transmission tunnel, rocker panels and center console. “The end result is a cooler and quieter Slingshot, allowing for longer rides and improved rider comfort.”
Founded in 1995, DEI is a major manufacturer and supplier of high-performance automotive aftermarket products selling worldwide to all sectors of the international powersports market and specializes in the development of thermal and acoustic performance products.


Barnett Clutches & Cables

Clutch kit for 2017 FL Touring models

Ventura, California based manufacturer Barnett Clutches & Cables has responded quickly to one of the commonly heard complaints about Harley's 2017 M-8 powered Tourers, namely that the existing stock clutch set-up could do with some help to handle the additional power available from the new engine.

This direct-fit upgrade clutch kit for the 2017 Harley-Davidson FL Touring models is just the latest in a long line of stock upgrades offered by Barnett down the years. It features Barnett’s segmented Kevlar friction plates, which are designed for more oil flow, longer life and smoother clutch operation.
Also included are 10 Kevlar friction plates, 9 tempered steel drive plates and a set of three heavy duty clutch springs. Barnett say all their kits are quality checked for exact stack height prior to packaging to guarantee proper fit and optimal performance. Barnett tempered steel drive plates go through a vibratory deburring process and are then checked for flatness; heavy duty Barnett clutch springs are pre-set, shot-peened and heat treated for performance and durability. Made in-house by Barnett.


Avon Motorcycle Tyres

Avon adds new Cobra touring sizes

Leading custom tire manufacturer Avon has added to its ever popular Cobra range of touring tires with two new fronts (130/60B19 and 130/60B21) and two new rears (160/70B17 and 180/55B18).

Avon has two new front and rear Cobra touring sizes

A firm favorite with custom shops, custom bike builders and performance custom engineers, Avon’s Cobras were introduced in 2007 as a replacement line for the venerable Venoms. Described as delivering “style and performance for cruisers, customs and tourers,” they are backed by Avon’s Road Hazard Warranty program and 15,000 mile warranty.
The construction is said to incorporate sports tire technology for nimble handling with a “special construction to deal with heavy loads.” They are said to have “incredible stability and longevity, making them perfect for touring with their snakeskin effect sidewalls and Cobra head on the shoulders adding a great custom styling touch to any V-twin.”


Noted as “ultra-quiet” tires, Avon offers extra wide sizes for custom applications in a wide range of sizes for Harley-Davidson’s V-Rod and V-Twin Baggers, Triumph’s Rocket III, Honda’s Goldwing and Valkyrie, as well as the sizes for custom bike applications.
Avon is currently also introducing a new size for Adventure sport models (150/70R18) and the Spirit ST - a new sport touring range.


JRi Shocks

JRi Shocks launches Harley fork cartridges

Mooresville, North Carolina based JRi Shocks has introduced fork cartridges to round out a Harley-Davidson suspension product line that includes standard and single adjustable rear shocks – these new fork cartridges are tuned to work in unison with JRi rear shocks.
“Customer demand drove us to add this to our product line. I put as much time, detail and attention into this product as I do with any high-performance racing product. I was so impressed with the fork cartridges and with the first time testing, showing that this addition could make you forget you’re riding a 700 plus pound motorcycle,” says Jeff Ryan, JRi Shocks’ founder and Technical Director.
The JRi fork cartridges replace all of the Harley-Davidson fork internals for the Glide family, model years 2014 to 2017, and are constructed from all aluminum aircraft grade parts. The piston design allows for “dynamic low speed and high-speed control, improving front brake diving, stability, cornering and bottoming control,” according to Ryan.
Founded by Ryan in 2007, JRi Shocks offer shock systems for all vehicle platforms, including, but not limited to, drag racing, motorcycle, off-road, road racing, short track racing, stock car racing, street performance, OEM needs, and other transportation platforms such as planes, boats and trains, bio-mechanical/cyborg devices and numerous applications within the defense/military sector.


J.W. Speaker

Adapt and evolve

The J.W. Speaker Adaptive Series headlights represent a genuine evolution in motorcycle headlights, described by the Germantown, Wisconsin based manufacturer as “the world’s first dynamically adaptive motorcycle headlight,” designed to address the issues of lighting blind spots created by fixed lights when a motorcycle is leaning or cornering.”

The Adaptive Series headlights use on-board sensors and advanced electronics to calculate bank angles on a real-time basis, automatically directing the light array up or down as the motorcycle leans. This additional illumination fills the gaps that stock headlights leave when cornering at night - intelligently “tuning” low beam and banking optics in a way that maximizes visibility in corners.

These adaptive headlights are designed with an integrated optical system that includes both an adaptive low beam as well as J.W. Speaker’s proprietary ComfortLite high beam. Together these optics are said to provide best-in-class foreground illumination and light above the horizon that dramatically improves operator comfort and safety for night-time driving.
Made with a heavy-duty, die-cast aluminum housing, state-of-the-art LEDs and “sleek design that not only delivers premium performance, but also gives the bike a truly unique look!”
Available as a plug ‘n’ play solution for 7″ round motorcycle fairings and 5.75″ round bucket mounts, they are DOT and ECE dual-compliant, and 18 different fitment kits available to make them a simple retrofit install on over 1,000 different motorcycles.”


Öhlins Racing

Retro 43

Swedish suspension specialist Öhlins offers a 43 mm conventional universal fork for any custom bike builder who wants to give the bike “supreme suspension performance.”

Featuring the familiar Öhlins Racing design in black or the well known Öhlins gold version, inside the fork is their proven and well known NIX technology, which features compression damping in the left leg and rebound damping in the right leg.
This allows for stable damping characteristics due to positive pressure build-up and a more precise adjustment, since the separated circuits don’t affect each other - adjustment for compression, rebound and spring preload are all easily and externally accessible at the top caps.
The company says that “this fork delivers stable characteristics while ensuring great bump absorption to give the rider a smooth and comfortable ride. The fork bottoms are delivered without brake caliper and fender mountings, which enables the fork to be easily adapted to various applications and models by the bike builder.”
These forks have a 130 mm stroke, 800 mm length, 43 mm triple clamp diameter and 9.5 N/mm spring rate with a range of optional spring rates available.
