2015 Freewheeler™ Trike

2015 Freewheeler™ Trike

The wait is over!

According to the Harley-Davidson press release here’s what’s new in 2015:

Freewheeler™ Trike – From its mini ape-hanger handlebar to its bobtail fenders, the Freewheeler trike fuses custom style and easy-handling performance. The all-new rear body shape gives the Freewheeler a low, lean profile.

Braking System for Softail® Models – A new braking system for Softail models delivers improved modulation and responsiveness and decreases hand lever effort by 40 percent. ABS is now standard on all Softail models and optional on the Slim. New front brake components include a rigid four-piston fixed front brake caliper with 34 and 32mm pistons coated to minimize initial displacement, brake pads with high-output friction material, a new master cylinder with a higher mechanical ratio, and a new 300mm front brake rotor. The caliper and master cylinder have been restyled to enhance the looks of each model.

Electra Glide® Ultra Classic® Low / Ultra Limited Low Motorcycles – A package of ergonomic enhancements that offer the lowest seat height and highest rider confidence available in a premium touring bike, combined with a full complement of Project RUSHMORE features and classic Harley-Davidson style.

2015 Street Glide

2015 CVO Street Glide

CVO Street Glide Motorcycle – It’s back!  The CVO Street Glide has a new Boom! Audio system with 600 watts of power streaming through four bi-amped front and rear three-way speakers.  It’s a limited-production bagger to achieve that rolling concert “bubble” with volume and sonic quality that will shock the neighbors. There will be four color options with an intricate paint scheme.

CVO Road Glide Ultra Motorcycle – This was a CVO surprise given the new release of the new 2015 Road Glide and many thought it would be a year before a CVO version would launch.  This a super-premium touring motorcycle with world-class aerodynamics, luxury touring essentials and the performance of a Screamin’® Eagle Twin-Cooled™ Twin Cam 110™ engine.

You might recall that Harley-Davidson previously announced the 2015 Road Glide before Sturgis.  It was also included it as part of this press release:

2015 CVO Road Glide Ultra

2015 CVO Road Glide Ultra

Road Glide® Motorcycle – After a model year hiatus, this bagger is back with a new triple vented, frame-mounted fairing, Dual Reflector Daymaker™ LED headlamps and a new handlebar with reduced reach and a new wrist angle for improved ergonomics.

Road Glide Special® Motorcycle – The Road Glide Special is equipped with premium Boom! ™ Box infotainment, upgraded suspension, and Reflex™ linked brakes with an Anti-lock Braking System (ABS).

So what do you think of the new models?

Harley-Davidson ABS Model List

Harley-Davidson 2014 ABS List

The European Parliament mandated that all new motorcycles and trikes sold in Europe with engines larger than 125cc are required to have ABS by 2016, and because of “global harmonization” – a term to describe manufacturing vehicles to uniform standards – suggests that the requirement will make ABS much more common in the U.S.

I would have anticipated a bigger push for ABS because the rate of fatal crashes is 31 percent lower on a motorcycle with antilock brakes than in the same models without ABS, according to research by the Insurance Institute for Highway Safety.

Thirty-one percent is a big number.  Or about one in three motorcycle crashes that could possibly be avoided.

With ABS, riders stop more quickly and stopping distances improve on wet and dry surfaces. ABS reduces concern that the wheels will lock up, which might result in a skid. Locking up the brakes in a panic stop robs the rider of any steering control which can easily lead to a skid and crash.  In the often wet northwest riding environment, maintaining control of steering during an emergency stop is most valuable.

ABS is becoming increasingly common on larger motorcycles.  In fact, BMW Motorrad USA started making ABS standard equipment on all its motorcycles beginning with the 2012 model year.  In the above photo is a list of 2014 Harley-Davidson models that include ABS.  One concern is that it’s been difficult to find ABS on smaller motorcycles.  Those smaller motorcycles are often purchased by less experienced riders, who are likely to benefit most from ABS.

From my vantage, if you don’t have ABS brakes it’s one of the best incentives to consider trading/buying a new motorcycle that does.

14-Touring-RecallHarley-Davidson is recalling 66,421 Touring and CVO Touring motorcycles from the 2014 model year because their front wheels can lock up without warning.

The motor company says the front brake line can get pinched between the fuel tank and the frame which could cause front brake fluid pressure to increase, increasing the risk that the front wheel could lock up while riding. Motorcycles with anti-lock brakes built between July 1, 2013, and May 7, 2014, are included in the recall.

NHTSA Campaign Number: 14V-319

Components:
SERVICE BRAKES, HYDRAULIC

Potential Number of Units Affected: 66,421

Problem Description:
Harley-Davidson Motor Company is recalling certain model year 2014 ABS-equipped Touring and CVO Touring motorcycles, models FLHTK, FLHTKSE, FLHTKSHRINE, FLHTCU, FLHTCUTC, FLHTP, FLHX, FLHXS, FLHXSHRINE, FLHR, FLHRC, FLHP, and FLHRSE, manufactured July 1, 2013, through May 7, 2014. The affected motorcycles may have been assembled with the front brake line positioned so that it can be pinched between the fuel tank and frame causing the front brake fluid pressure to increase.

Consequence:
A pinched brake line will increase the front brake fluid pressure, possibly resulting in a front wheel lock-up, increasing the risk of a crash.

Remedy:
Harley-Davidson will notify owners, and dealers will inspect the motorcycles for brake line damage and replace the damaged lines as necessary. Dealers will also install one or two cable straps to properly prevent the line from being pinched in the future, free of charge. The recall is expected to begin in July 2014. Owners may contact Harley-Davidson customer service at 1-800-258-2464.

The chronology of events leading up to the recall:  Harley began an investigation on September 11, 2013 after it was “advised of a pinched brake line under the rear fuel tank mounting bracket of a police motorcycle being set up for service.”

On October 8, 2013, H-D determined that “six warranty claims/consumer contacts” were potentially linked to the brake line issue. Among those six incidents were “one crash with no injuries.”

Within a week corrective action was taken on the final assembly line at the York facility, as on October 14 a cable strap was added to retain the brake lines from being pinched under the aforementioned fuel tank mounting bracket. H-D reports it then closed its investigation on November 11, 2013.

However, the investigation was reopened on May 7, 2014 when the York Final Vehicle Audit “reported a Touring bike with a brake line pinched in a different location, between the fuel tank and the frame several inches forward of the rear fuel tank mounting bracket.”

Harley-Davidson added another cable strap to the production process addressing the issue at the new suspect location. The company subsequently reanalyzed its warranty data on May 12, reporting “a cumulative total of 39 warranty claims potentially related to this issue, four of which reported crashes (with one reported minor injury).” On May 20, it determined another “customer complaint involving a reported crash with minor injuries” was related to the front brake line issue.

In total the company knows of five crashes and two minor injuries related to the defect.

K1200 GT

This week Toyota paid a $16.7M civil penalty for not notifying the NHTSA of a dangerous pedal defect.

Certainly Harley-Davidson has had its fair share of defects and needed to recall motorcycles in 2008 HERE, 2009 HERE and then again in 2009 HERE.

Now it’s the German motorcycle manufacturer BMW’s turn.

This week they launched a global recall of 122,000 motorcycles owing it to front brake problems.  The company uncovered a risk of leaks in the braking systems on its K1200 GT motorcycles and other models built on the same base.  The recalled models are R1200 GS, R1200 GS Adventure, R1200 R, R1200 RT, R1200 ST, and K1200 GT.  The recall concerns motorcycles built between August 2006 and May 2009, some of which have already been checked, according to a BMW spokesman.

“Over time, it emerged that even corrected braking systems did not resolve the problem 100 percent,”

The culprit seems to be vibration generated by the motorcycle’s operation which were found to cause leaks that affected the front brake.  The company stated that rear brakes continued to function normally.  BMW has not heard of any accidents linked to the problem.

As of this writing, BMW has yet to post information to the Office of Defects Investigation or onto the NHTSA site (Safecar.gov) about this recall notice.

Here’s an interesting video on the Harley 2008 Anti-Lock braking system. It’s a bit long (8min), but explained in detail.  It’s curious how during wet braking the rider stays upright and they talk about limitations of the system when over braking on corners.  As always the best braking method is “upright”.  Enjoy.
