NEW HARLEY DIRT-TRACKER


WITH the air-cooled, push-rod overhead valve XR750 now in its 44th year, there is plenty of speculation that Harley-Davidson will replace it with a racing version of its new 750cc water-cooled 60 degree V-twin.

Harley-Davidson has enjoyed incredible success with the XR750, but when it made its d├ębut back in 1970, no one would have predicted it would still be winning races in 2014. In fact in the first two years with the new overhead valve racer, Harley-Davidson’s race chief Dick O’Brien struggled to make it competitive with the English 750cc OHV parallel twins from BSA, Triumph and Norton.  Those first XR750s struggled to match the power output of the side valve KR750s they had replaced.

Then O’Brien and his team made a break-through in port design and started to challenge the competition, well on dirt-tracks at least.  In road racing, the XR750TT was struggling against Yamaha’s air-cooled 350cc TD-3 and pretty much outclassed by the water-cooled TZ350 that followed, let alone the three cylinder two-strokes from Kawasaki and Suzuki.  If that wasn’t bad enough, along came the four cylinder TZ700 and it was game over.

However, Harley’s fortune’s in dirt-track racing went in the opposite direction to the road-racers.  As the road-racing XR750TT struggled, the dirt-track XR750 got rolling.  Mark Brelsford was the first man to win the AMA Grand National Championship on the XR750.  That was in 1972.

But then Yamaha got Kenny Roberts onto a bored out XS750 dirt-tracker, and armed him with a TZ700 road-racer.  Kenny then went on to win back-to-back Grand National Championships in 1973 and 1974 before Harley-Davidson took over.  Later on the American Motorcyclist Association separated the road-racing series from the Grand National Championship so Harley had an even stronger grasp in that arena.

to win on the push-rod Harley.
However, with the series an all-Harley show, the AMA bowed to lobbying from Honda and allowed the limited edition overhead cam four-valve RS750 into the series.  Honda then went on a winning streak, taking the Grand National titles in 1984 (Ricky Graham), 1985, 1986 and 1987 (Bubba Shobert).

At this point the best RS750s were making around 125 bhp while the two-valve XR750s were making around 119 bhp.  This was staggering performance and it exacted its toll.  The Harley required frequent rebuilds and both brands ended some of the mile races on the cords of their rear tyres.

Scott Parker won a record nine  AMA Grand National 
Championships on the XR750, and racked up 
55 wins in mile races and 35 on half-miles.
The AMA was deeply concerned about this and introduced across the board 33mm intake restrictors.  This brought the Honda and the Harley down to 112-115 bhp.  With parity between the brands, Harley started winning again.  And it has kept on winning. But there’s a new challenger in the form of the DOHC, 8-valve liquid-cooled Kawasaki 650 parallel twin.

The Howerton Motorsports framed Kawasaki that 
Bryan Smith raced in 2012 and 2013.
It was former Harley-Davidson race technician Bill Werner who saw the potential of the Kawasaki twin and in 2010 he got former factory Harley rider Bryan Smith to race one.  Back then Werner was using the stock street bike frame.  Riding the Werner tuned Kawasaki, Smith won the Indianapolis Mile and the Springfield Mile a week later.

However, the Kawasaki struggled on half-miles and also had trouble getting traction off the corners on many of the other mile tracks, so Harley-Davidsons did most of the winning.

That has continued to this year.  Now riding for the Villa Esparza/Crosley Radio Team, Smith has Jeff Gordon-tuned, Kawasaki 750cc engines and many other components from the 2012 and 2013 Howerton Motorsports machine, in a highly modified C&J chassis by Robert Terando.

It has proved a winning combination and in July the team made another milestone, winning the Hagerstown half-mile.  This was the first time the Kawasaki had been able to beat the Harleys on a half mile.  And with wins on the mile tracks of Springfield, Sacramento and Colonial Downs, plus podium scoring rides elsewhere, Smith leads the GNC by nine points over Harley privateer Jared Mees with just two rounds remaining.

Bryan Smith has the  Villa Esparza/Crosley Radio Team Kawasaki out in front of the Grand National Championship with just two rounds remaining.  Will he be the first
man to take the title on a Kawasaki?

If Smith carries his points lead through the next two races, he will snatch the AMA Grand National Championship from Harley-Davidson’s grasp for the first time in 27 years.

That is not something Harley-Davidson’s stronger dealerships are going to take laying down.  So you can bet they have been beating on the factory door pleading for an XR750 replacement.

The 750 Street uses an all-new engine.  Will Harley-Davidson
use this as a basis for a new dirt-track challenger?
At the recent US dealer convention, Harley wheeled out a new water-cooled racer powered by the water-cooled OHC, 8-valve 750cc Revolution X engine from the new 750 Street.

Whether this is a factory deal or a Vance and Hines limited edition dirt-tracker remains to be seen.  Critics of the current MBA-dominated Harley management say they have seen precious little evidence that the current executives know anything about the company’s history, especially when it comes to dirt-track racing.

Perhaps they are about to be proved wrong!

RIDE WITH HONDA TO THE BURT...

NEW ZEALAND Honda motorcycle importer and distributor Blue Wing Honda is organising a ride from its new Auckland Airport headquarters to the Burt Munro Challenge at the end of November.

Quite a few of the Blue Wing Honda staff will be going on the ride, which will visit dealerships along the way. 

Dealer teams and customers are welcome to join in on the ride.

Here are the details from the team at Blue Wing Honda:

Following our national roadshow we want to introduce the Honda Rider tagalong to the Burt Munro.

We have mentioned that Blue Wing Honda team members will be travelling from Auckland to the Burt Munro Challenge (event in Invercargill, November 27-30) and we welcome any dealer team members, or customers to join the ride down.

The Blue Wing Team will leave from Blue Wing Honda on Friday, November 21 at 9am.
The planned itinerary is to pass through several Honda dealerships on the way down the line. We will visit both Cyclespot and Botany Honda in the morning before leaving Auckland.

We will be calling in at Honda Hamilton late morning, and then continuing to Waitomo where we will have our first overnight stop.  Day two will see us leave Waitomo, and head across country to Napier, via Waiuru where riders will have the option to visit the Waiuru Army museum.  From Waiuru we will travel up past Lake Taupo, calling through Erikson Honda in the afternoon.  Day two will then conclude in Hastings.
Day three will be the trip to Wellington.  Stops will be City Honda and Motomart.  Overnight in Wellington, November 23.

The South Island leg will commence on November 24.  We will head from Picton to Nelson, stopping at Morley Motorcycles.  From there we will head around the Nelson Lakes region, reaching Hanmer Springs for the overnight stop.

The November 25 will see us leave Hanmer and head down the east coast to Casbolts in Christchurch around mid-morning.  Following that we will head to Oamaru Honda mid-afternoon where we will overnight in Oamaru.

November 26 will see us make the trip to Invercargill for the commencement of the event.

All riders are welcome.  You may choose to do just part of the ride, some may choose to tag along for the entire trip.

The ride will allow us to showcase a variety of Honda product, and importantly have a bit fun along the way.  It is a great way to celebrate our brand.

The ride back will be at your discretion how you want to return, when you want to leave and which route to take.

OPEN HOUSE AT 'GUZZI FACTORY

FINAL preparations are underway at Mandello del Lario in anticipation of a peaceful invasion by Moto Guzzi fans who traditionally descend upon the lakeside town in northern Italy in the second week of September.

This year’s three day Open House will feature test rides on the entire 2014 Moto Guzzi range, free entry to the Moto Guzzi Museum and guided tours of the engine and vehicle production lines.  Guests will also get to see the most extreme and spectacular Moto Guzzi specials on display.

The 2014 range is available for testing...

On Friday, September 12, the famed red gate with the golden eagle at Via Parodi 57 will open to welcome enthusiasts who want to discover or relive the experience of visiting a unique factory.  This is an appointment with history to appreciate the industrial architecture, the ingeniousness of the wind tunnel – the first motorcycle factory to build one – and more than 150 motorcycles on display, from the original GP (Guzzi-Parodi) to the MGS01, as well as the first Normale, manufactured in 1921, which was returned to the Museum this year after an extensive restoration.

Moving on from the historically significant bikes to modern ones, this year visitors will once again have the chance to test the major models in the 2014 range, from the luxurious California 1400 to the refined V7 in all of the various versions, taking a ride which will lead to the entrance of Lecco and Varenna.  

A feature of the 2014 Moto Guzzi Open House which is sure to be popular is the Custom Area, where fans will be able to admire not only the major models in the 2014 range, but also the most prestigious “Specials” built on small and big block bases by the most famous "custom made shops" in the sector: RossoPuro, South Garage, Millepercento and the German Radical Guzzi bikes.

The bookshop will contain plenty of new articles with a sneak peek of the 2015 fashion and accessories collection as well as the chance to purchase the previous collections at outlet prices.

In the spirit of the hospitality and warm welcome that makes Mandello a place any biker loves, this year visitors will be able to camp for free in the Lido area under a starry sky (at least that's what everyone is hoping for!) and with one of the most beautiful views of the Lario.
