Amongst the top riders at the Isle of Man TT, victory or defeat can come in pit lane, as crucial time is either won or lost in front of the TT Grandstand on Glencrutchery Road.
But, a pit stop at the Isle of Man TT is not a straight-forward affair, and as such the top teams have choreographed a precise dance in order to extract the maximum performance under tight circumstances.
For TT riders, the biggest rate-limiter during a pit stop is fuel, and a good pit stop will see teams waiting for their fuel tanks to fill, rather than losing time on changing a rear tire, attending to the rider, or some other mechanical issue.
In the video attached to this post, we see Peter Hickman come into the pits, on his way to winning this year’s Senior TT – setting a course record of 135.452 mph along the way as well. It is an interesting insight into this often over-looked aspect of TT road racing.
New model teething issues are always a reality, and it seems that the Ducati Panigale V4 is no exception to the rule. Finding not one, but two issues with the Panigale V4’s fueling system, Italy’s newest superbike is being recalled in the United States. Both recalls seem to affect the full-lot of Panigale V4 models that have made it to US soil thus far this year, which means 692 units (base, S, and Special trim levels) are being recalled for two issues related to the bike’s fuel system. As such, the first recall centers around the breathing system valve plug on the Panigale V4, which might have a fuel leak if the O-ring was damaged during production. Accordingly, the second recall involves the fuel tank cap, which can spray gas when opened, because again of breathing issues within the fuel system.
KTM 1290 Super Duke GT owners should expect a recall notification in the coming weeks, as the Austrian brand has determined that there is an issue with the sport-tourer’s fuel hose.
The recall affects both 2016 and 2017 models, and centers around the possibility that the installed fuel hose may develop small holes or cracks, which could lead to fuel leaking from the fuel hose. As such, it needs to be replaced by a certified KTM dealer.
It’s 2017 and the Two Enthusiasts Podcast crew is back into the swing of things, bringing you a slightly irreverent perspective on the motorcycle industry.
To get the new year started off right, we have an extra long Episode 42 for you, which covers all of the major stories from last year – what bikes were hot, what news items were important, and a review of the racing season await you.
We’ve got some interesting shows lined up for 2017, and we think you’ll enjoy how we’re starting off this next orbit around the sun.

In addition to the recall for its brake pressure switch, two more recalls have been filed by Polaris for its Slingshot three-wheeler. While both additional recalls affect nearly the 18,000 units that have been made in the lifetime of the Polaris Slingshot, they differ in cause.
The first recall is for the Polaris Slingshot’s rear swingarm, which filings say may not have adequate strength for its application. Polaris dealers will inspect the swingarm, and if necessary, repair/replace the swingarm free of charge. Polaris’ number for this recall is T-16-06.
The second recall is for the hood on the Polaris Slingshot, which may not have enough clearance with a fuel line. Polaris dealers will inspect the fuel line’s retention clips, in order to reduce the risk of interference. Polaris’ number for this recall is T-16-03.
Every month, the American Motorcyclist Association (AMA) releases notes on the various happenings and movements that are occurring in the two-wheeled political landscape. September being no different, one of the AMA’s line items is the return of a four-gallon minimum purchase recommendation of E15 fuel, courtesy of the American Coalition for Ethanol. If this issue sounds familiar, it is because a similar provision was put forward by the EPA back in 2012, but was ultimately withdrawn when it was clear most motorcycle carried only 3-5 gallons of gas, and were not EPA-approved to run E15 fuel. I wasn’t planning on rehashing this story when the AMA’s note came out, but since there have been a few reports with some inaccurate information, I thought it best to address what is going on with E15 fuel this time around.
It is but a short trip up the road from Spielberg to Brno, but it is a journey between two very different worlds.
From the hyper-modern facility at the Red Bull Ring, to the frayed-around-the-edges buildings of Brno. From a track which has been missing from the calendar for the best part of twenty years to a circuit which has seen racing almost since its inception, where teams often come to test.
From a track with a paucity of corners, all hard braking and acceleration, to one which flows from corner to corner, where bikes mostly exit in third gear when getting on the gas.
The starkest difference between the Red Bull Ring and Brno is the layout. Both tracks snake up and down hillsides, but where Austria is a track stuck up against a mountain, Brno is a winding road which threads its way through hills and vales.
Where Spielberg is basically seven corners, three of which are almost hairpins, all fourteen of Brno’s corners are long and flowing.
Ironically, Brno’s flowing layout makes it somewhat more simple to set up a bike for it. All of the corners are similar, with no camber and needing the same approach.
“The set up is more important than at other tracks because all the corners are similar,” Danilo Petrucci explained to us on Thursday. “You have to be good on braking and especially the feeling of the front. Because for more than 50% of the track you are on the edge of the tire.”
So much for Ducati domination. Sure, the two factory Ducatis are on the front row, Andrea Iannone on pole, Andrea Dovizioso in third, but they did not destroy the competition in qualifying the way they did so in practice on Friday.
Austria is still Ducati’s best chance of a win since Casey Stoner left for Honda at the end of the 2010 season, but it is no longer the sure thing it seemed on Friday.
What happened? A lot of things, but most of all, the weather improved dramatically. That certainly helped Jorge Lorenzo find some confidence, and put him back into contention after a couple of tough races. Valentino Rossi found some acceleration, and improved his pace.
Marc Márquez worked on making up on the brakes what he is losing in acceleration. That puts the Ducatis, the Yamahas, and Márquez all within a tenth or two of each other in race pace. We really are going to have to wait for the fat lady to start singing on this one.
The Grand Prix Commission have filled in the last question marks over the 2016 MotoGP regulations. While the decision on the amount of fuel the bikes would be allowed to run had already been decided last year, the rules on a minimum weight, the number of engines to be used, and how and whether the concessions allowed to manufacturers without a win would be extended into 2016 and beyond. All of these questions were settled at Qatar. The GPC meeting, where Dorma, the FIM, the manufacturers and the teams meet to agree a set of rules, confirmed that all bikes in MotoGP next year will use 22 liters of fuel.
Once upon a time, Grand Prix racing rules were fairly simple: bikes had to have two wheels, weigh 130kg, have a maximum capacity of 500cc and a maximum of four cylinders. The switch to four strokes in 2002 added a lot of complexity to the rules, and things have been getting slowly worse since then.
MotoGP now has two different categories with three different rule sets covering a single class, depending on entry type and results in recent years.
With Suzuki and Aprilia entering the series in 2015, and another rule change on the horizon for 2016, it’s time to take a quick look at the rules for this season, and see what has changed since last year.
The news that Honda would be building a production racer to compete in MotoGP aroused much excitement among fans. There was much speculation over just how quick it would be, and whether it would be possible for a talented rider to beat the satellite bikes on some tracks. In the hands of active MotoGP riders, the gap was around 2 seconds at the Sepang tests. Nicky Hayden – of whom much had been expected, not least by himself – had made significant improvements, especially on corner entry. The difference in performance and the big gap to the front has been cause for much speculation. Where are the Honda production racers losing out to the Factory Option bikes?
