A New Period Begins for AFT


The introduction of Indian Motorcycle’s FTR750 flat track racer brought another manufacturer into the fray, but it isn’t without its issues.

Those that have adopted AMA racing coverage improvement over time have remarked on the distinction between the sensibilities of AMA’s Ohio-based administration and people of the numerous “fixers” and “czars” who’ve been employed to rework US flat-track racing right into a profitable enterprise.

Czars have been advised to clear their desks and be passed by midday when modifications they made offended administration or proved ineffective.

2015 was a departure, for in that yr a really skilled motorbike business supervisor and promoter, Englishman Michael Lock, was employed to direct the way forward for what’s now known as American Flat Observe (AFT). A five-year plan was put in place, of which a robust ingredient has been dirt-track TV protection by way of streaming.

After I just lately spoke with Lock he stated, “On the finish of 2015, starting of 2016 we laid out a technique for progress. We separated twins and singles. We wish the lessons to be clear to spectators—singles right here, twins there.”

A general plan was to implement NASCAR’s profitable give attention to placing as many manufacturers on the beginning grid as doable. The objective was to base AFT’s premier class on modified production-based engines—breaking with the previous dominated since 1972 by race-only designs reminiscent of Harley-Davidson’s XR750 and Honda’s RS750.

Lock continued, “Again within the earlier period there was utter domination by the XR and RS—very totally different from the avenue.”

The objective regarded practicable as a result of there have been now quite a few mid-displacement mass-produced bikes—the Kawasaki Ninja 650, Yamaha MT-07, Triumph, and KTM parallel twins, and vee engines from Harley and Ducati. These have been fashionable designs able to excessive efficiency. This may stoke the recent model rivalries believed important to reaching spectator engagement and partisanship and would supply builders with recent materials.

Lock would obtain a breakthrough by persuading horse to observe operators close to massive cities to offer flat-track motorbike racing an attempt. That introduced recent spectators to the game and opened new potentialities in TV.

Whereas these plans have been formulated, Indian bought in contact with AFT. Lock continued, “Indian wished to determine themselves versus Harley-Davidson in some form of (aggressive venue). They have been desperately eager however had nothing appropriate in manufacturing. The rule ebook nonetheless allowed a race-only 750 engine.

“We have been delighted and it was a technique to reintroduce flat observe as an all-American sport [reviving the old and deep Harley-Indian rivalry]. We had that settlement with Indian—they wished to have a two-year run with FTR [the race-only 750 V-twin they were building]. Indian stated, ‘Look, it is a stopgap. Allow us to compete to 2019.’”

Indian gained the AFT Twins championship in 2017 and 2018, after which a second and separate twins class—Manufacturing Twins—was added to occasions to permit groups to organize for the deliberate way forward for only one twin’s class in 2023, powered by production-based engines.

“Free of manufacturing’s restrictions, you possibly can produce an actual weapon,” Lock continued. “Nobody then knew how dominant it might be—Indians got here to make up two-thirds of the grids. We hoped Indian would substitute the FTR with one thing usable from the manufacturing aspect.”

Polaris, which owns the Indian model, is an aggressive firm with sturdy sources. It constructed what was required to win in AFT. Indian’s success was no shock, provided that Harley’s XR was stretched to its restrict and that no different producer was stepping up with a completely engineered AFT twins bundle.

Keep in mind that whereas the long-serving XR had an air-cooled pushrod engine, all the brand new engines working in AFT Twins are liquid-cooled (permitting use of upper compression ratio) and have double overhead cam valve drive (which makes it simpler to realize a controllable flat torque curve).

For personal groups, relations with producers are like what we’ve seen in World Superbike. Producers not actively in that collection quietly provide non-public groups manufacturing facility elements or different assistance “within the close to future.” The elements and assistance accomplish little past retaining hope alive.

Lack of manufacturing facility dedication in AFT isn’t shocking—motorbike gross sales within the US took a 60 % hit in 2008 and the business has since provided senior workers early retirement and moved operations out of California to lower-wage, lower-tax, lower-real-estate-cost areas.

AFT is a nationwide and even regional sport, limiting its gross sales leverage, making manufacturing facility assist exhausting to draw. Wanting again, earlier than Indian, solely Harley-Davidson and Honda designed and constructed race-only dirt-track engines. Harley and contractor Vance & Hines have since 2017 fielded the XG750R dirt-tracker, based mostly on the manufacturing Avenue 750 mannequin (now not bought within the US). The V&H function in that has now ended.

A protracted-serving Honda supervisor defined to me again in 2015 that there was a traditional shift throughout the business. Managers were motorbike folks of lengthy expertise however in the present day their replacements are likely to have generic gross sales and public relations coaching, and racing shouldn’t be one thing they perceive.

We see this within the business’s response to MotoAmerica’s efforts to rebuild US road racing. At first, folks thought US road racing had simply been mismanaged and had stalled. Possibly all that was wanted to revive it was to crank it over till it began. MotoAmerica has completed lots however all their diligent cranking has but to revive a lot of the previous degree of producer assist of racing.

On this local weather, any provision of assistance from a producer was welcome to AFT—even when it conflicted with their five-year plan. Indian was given the go-ahead for its race-only FTR dirt tracker.

“Indian initially thought they’d construct perhaps a dozen FTRs,” Michael Lock stated, “however they ended up making 50 and even 60.”

Such quite a few FTR gross sales proved there was a tools vacuum in AFT. Individuals have been prepared to scrape up the money to purchase an Indian relatively than deal with modifying a manufacturing engine. The FTR was so engaging as a result of it being a turn-key aggressive motorbike.

Lock identified that there are two tiers of groups—these able to do their very own engine improvement, and people whose budgets are stretched simply to afford the fundamental tools.

The pure result’s that a lot of the profitability is completed by that first tier. “Racing is now pointed on the high—perhaps 5 guys doing all of the profitable,” stated Invoice Werner, former Harley-Davidson manufacturing facility flat-track builder/tuner who helped Scott Parker win 9 nationwide championships between 1988 and 1998. “Harley pulled out, leaving one group. Now there’s only a handful of bikes. There’s higher racing in 450.”

Manufacturing Versus Race Design

By the top of 2019 Indian had not launched a manufacturing mannequin able to be transformed into a motorbike for AFT’s Manufacturing Twins class.

Right here it’s mandatory to know some variations between manufacturing and race design. Manufacturing engines are designed for low-cost manufacture, reasonable efficiency, and to fulfill buyer tastes. This means low element counts (for instance, single overhead cam relatively than double, two cylinders relatively than 4, and many others.) and infrequently, excessive weight.

Many V-twin riders like their bikes to feel and look massive. When Vance & Hines took the contract to develop Harley’s Avenue 750 manufacturing engine (in the marketplace 2014–2020) into the XG750R flat-track race engine, it was initially dumbfounded by the stocker’s sheer mass. Then V&H understood the load that may very well be saved by redesigning many elements to be milled-from-billet in CNC machining facilities.

Lest the reader gets the concept the Manufacturing Twins class is cheap, take into account that the primary bike to win a championship in our period—the Kawasaki 650 Ninja—was profoundly modified with all of the zeal and cleverness of the American scorching rod.

Indian’s VP for racing, know-how, and repair Gary Grey stated, “I’ve heard rumors that everyone else is welding and machining their crankcases. On the high, the consumption track shouldn’t be manufacturing.

The throttle our bodies shouldn’t be manufacturing. The valves, valve springs, seats, and cams shouldn’t be manufactured. Right down to the cylinders—they shouldn’t be manufacturing, the pistons, the rings, the connecting rods, the crank. They (Manufacturing) can run exterior flywheels and we can’t. Clutches? Not manufacturing. Transmission? Not.”

It’s doable that the Indian FTR at $50,000 is a little dearer (and maybe much less so) than what it prices to develop the profitable mixture for “eBay motors” just like the Ninja twin. The hope, naturally, is that there will probably be sufficient demand for the required “trick elements” to curiosity an aftermarket in tooling and producing them.

Such intensive modification brings us to a query that will develop into necessary in the future: How does AFT outline “manufacturing”? In its guidelines, I see expressions reminiscent of “mass manufacturing” and “avenue” however nothing near the precision of FIM guidelines for manufacturing homologation.

What number of machines have to be produced to be homologated? Is there a worth restricting? Which elements should stay as-produced?

Though AFT’s tech director David McGrath says, “One of the best rule ebooks is a thin one,” the tendency of contemporary sanctioning our bodies is to repeatedly alter their guidelines. That is sensible in F1, the place the highest groups ever spends over 1 / 4 billion dollars yearly, and it could work in MotoGP at one-tenth of that.

However, in a nationwide collection like AFT, the groups can’t simply assign an engineering group to every week’s guidelines modifications. Guidelines modifications price groups cash.

Learn how to deal pretty with Indian’s success in Tremendous Twins and transition throughout 2022 to only the Manufacturing Twins in 2023? “We’d relatively make parity than kill the Indian,” Lock stated. “We’ve had very delicate conversations with Indian on how one can do it.

For 2022, AFT has mandated 34mm intake restrictors for race-only engines.

“Along with consumption restrictors we checked out weight, flywheel weight limits, a rev restrict, and weight of rear-wheel meeting.”

No group that has paid $50,000 every for a number of Indian FTRs can afford to have that worth destroyed. Realistically, AFT can’t afford to doubtlessly lose Indian’s present 50 or 60 track-ready bikes.

One technique to preserve the Indians within the collection is due to this fact to cut back their efficiency to realize parity with Manufacturing Twins this yr. One other approach is to create a spec class for the Indian.

Spec racing has grown worldwide as a result of it eliminating the heavy price of engine R&D from group budgets in a period when fewer and fewer folks have the required abilities.

Consider NASCAR and their standardized “Automobile of Tomorrow.” In that world, efficiency parity is the holy grail, so it’s tempting to freeze know-how to stop the “destabilization” of a category by a technologically superior automotive.

With respect to AFT’s Manufacturing Twins class and its uncontrolled engine modifications, some at the moment are asking, “What occurs if KTM is available in with one thing destabilizing?”
