Boom!!! In more ways than one...


I myself am an engineer, and if I can consolidate how everything went for a test or design in just a few words, everyone is better for it. So, if you are like me and want the weekend in a nutshell, here it is;
- 4 bikes (3 to Willow, 1 to Bonneville)
- 3 riders (Jeremy Toye, Gary Orr, and Andy Sills)
- 2 crashes
- 1 twisted knee
- 1 busted ego
- 1 run in with a bird at 120 mph
- 2 locked motors
- Lots of tires
- 4 wins
- 2 lap records
- 1 world record
- 2 Championships
Now, if you are also like me and become interested when the results of a test or weekend are so dynamic, keep reading!
This was going to be Gary’s first ride back on the S1000RR since he had finished his 10 n’ 10 rally, and it was going to be the first time both of the riders had a chance to try out the new Turner Curve (T.C.) suspension linkage at Big Willow. The first ride on the new parts felt good for both riders. Orr noted that the bike felt more comfortable, while Toye loved the feeling through turn 8 and the turn in characteristics. That was pretty much it for the day! With the Trackdaz event being so popular the amount of traffic in each session was too much for putting in consistent fast laps. Aside from that in the third session of the day another rider’s bike had a seal fail and oiled the entire track from turn 6 all the way to eight.


Luckily neither rider was involved, but Jeremy’s B bike was. Chris Ulrich was working on a press intro from Pirelli, and borrowed Toye’s spare bike since all of his equipment was in Alabama for this weekend’s final AMA round at Barber. Ulrich spotted the mayhem ahead of him when coming down the hill in turn 6, but due to the lack of attention of the flagger, ended up rolling right through the oil, losing the front end and damaging the bodywork on the bike. It wouldn’t be so bad if this were all that happened, but Chris tweaked his ankle pretty bad and because the bike was on its side while running the motor hydrolocked and destroyed itself.
At this point team Toye decided with the traffic, track conditions, and an already positive feeling from the bike we would take the rest of the afternoon off. I’m sure it had nothing to do with the fact that close by there was a pretty fun motorcross track, and Toye just happened to have his dirtbike in the back of his truck. Gary hung out and did end up making some progress in the last session of the day when the track started to come back in. So now we could look forward to some positive track time on Saturday, or so we thought.
Turns out that wouldn’t be the case. As Toye took to the track with the slightly used race compound tires he noticed a major issue with edge grip in turn 2. The same problem wasn’t evident anywhere else on the rest of the track leading us to believe it was a geometry issue. This situation was made even worse when we found that the practice sessions were also going to be cut short for the endurance race that was going to be held in the afternoon. Many different settings were tried in order to get the grip back that we had last month, but to no avail.
It wasn’t until well after practice was over and the team had a few hours in the think tank that a theory had formed. With the introduction of new parts comes new things to keep track of, and what basically happened is a shock measurement was set incorrectly based on how we modified the bike for the new T.C. linkage at Fontana (the previous round). Before we left for Jonny Corino’s (one of the team’s favorite places up in Palmdale) we made the necessary adjustments and kept our fingers crossed for Sunday morning practice.
Was it going to work, was it the right theory? All of the team’s questions were answered when Toye blasted a 1:19.861 in first practice on the hard compound race tires! That is unheard of in recent years and gave the team great confidence for the second practice to put in a few good laps on a new tire, but it wasn’t to be.
In any manufacturing industry, like the auto industry for example, not every single run is perfect (i.e. lemons). Well in the world of motorcycle tires it is the same, and not everyone is going to be a ringer. You’ve probably even heard about it before when Spies or Hayden would say in their interviews that their first “Q” wasn’t quite there, but the second tire was much better. Unfortunately the same thing happened to the number 57 when we sent him out for his second practice, and instead of him having the chance to run laps faster than he ever had before he ended up in the dirt.
When the bike came back in Toye said the tire just wasn’t there, “It spun like crazy in places I’ve never had a tire spin before!” The worst part of the crash was that there was only 30 minutes to get ready for his first race, and when the bike fell over on Jeremy it tweaked his knee. After further discussion with the team, we were going to try making the race and he was going to give it his best riding.
I kid you not when I say that the final bolt was going in right at the very last second before he would be able to make the warm up lap, but SD BMW had made the grid. The worst part for the team was that right after the green flag flew and the riders disappeared from sight the race was stopped. A rider had fallen down in turn 2. The seconds it took for all the riders to return to view seemed to pass like days, but both Gary and Jeremy made it out unscathed and returned to the hot pit. Gary was doing fine and Jeremy said the bike was ok.
Now it took Jeremy a few laps on the restart to really get back up to speed. One would have to understand that he needs time to make sure he’s going to be ok, the bike is going to be ok, and start to trust the grip from the tires. On lap five Toye was back, and let everybody else know by setting a new Open Modified Production lap record of 1:20.580! He won the race, but Orr didn’t fare so well.
While breaking for turn one at over 160 MPH the engine locked up on him, and was forced to retire from the race with a DNF. When he returned to the pits in the crash truck everyone was please to see that he was ok and the chassis was clean. The technicians tired to find what caused this lock up, but didn’t have any luck. For at least this day the number 517 was down and out. It would be the 57 machine that served as the teams work horse for rest of the day!
Toye’s a bike was used by Gary in Formula 40 to win by a country mile and wrap up the California State Championship. Jeremy hoped back on for races number 7 and 13 later to take a win/lap record in Open Superbike of a 1:20.142 and then lead every lap of the F1 race, and put his stamp on the premier title for the California State Championship!


For the full teams last stateside event it was nothing less than exhilarating. Over the next month and a half one part of the team will be getting ready to return back to the Streets of Willow with the number 517 to continue demonstrating the BMW S1000RRs race prowess while the other side of the garage will be hopping on a plane aimed for Hong Kong! Jeremy has received another invitation to the Macau Grand Prix that takes place on the 18th – 21st of November. Eager for some international competition we’ll be making 100% sure that all our ducks are in order with some extensive testing, new parts and preparation of a 220+ hp power plant!

Testing leads to domination in Sunday’s WERA West Races for Toye and the San Diego sponsored S1000RR!!

Autoclub Speedway saw clear skies and high temperatures for this past weekend while WERA was in town for their sixth round of the season. Aside from the unusually warm temps (108°F on Sat) the conditions were perfect for the team to get in some much needed testing. With new parts fresh out of the engineering department the team needed time to evaluate each component.
On Saturday we started out with a setup very similar to that of Infineon as there is a lot of very hard breaking at Fontana (see fig. 1).

Figure 1: Turns 3, 5, and 12 are some of the hardest breaking zones you'll find!

At this point breaking has always been an issue for us. From as far back as Buttonwillow and Miller we’ve been dealing with the S1000RRs unruly characteristics on the binders. Toye couldn’t feel exactly where the rear tire was and if it did step out it was a slap in the face when it came back in line for corner entry. That is exactly what we were trying to address this weekend with the new linkage.
In the first session we were on too stiff of a shock spring as evidenced by the notorious headshake that Jeremy was getting on the back straight between turns 9 and 12. So after a quick spring change Jeremy had a safe motorcycle again and we could get to work. The next session out we were able to dial in gearing and focus on the areas that really make a good bike at Fontana. Here, not only does a bike have to be ubber stable on the breaks, but it also has to be up for ultra quick direction changes and pulling the trigger as hard and fast as possible. After a few sessions in the morning we had a good overall setting on the stock equipment and it was time to start testing the new parts after lunch.


The picture you’re looking at is a 3D model of the modified linkage assembly that our team engineer has developed. Although they perform the same function as the stock components the dimensions and angles of the new parts SHOULD make the S1000RR even better! The keyword here is, should. If there is one thing that we know it’s that something may look great on paper, but until you put it in a real world application (in our case that’s on track) it’s just a crap shoot. Lucky for us it worked just as well on the bike as it looked on paper!
It did take us the rest of the afternoon to get the dampers and the geometry to work with the new ratios in the linkage, but the bottom line is the results. Sunday morning when we put Jeremy out on new tires he flew! Now with the power of the BWM S1000RR rocketing him off of the corners he also had the feel and confidence to bring it down on the binders like he’d never had before. The bike was fun for him to ride again, and it showed.
When it was time to race Jeremy took the holeshot in both of his races and never looked back. By the end of the first race he had a 19 second gap back to second, and that’s in just six laps! The S1000RR owned everybody on the banking and now that Toye had a bike underneath him that is, “by far the best it’s ever been” he owned everybody in the turns too. A lot of the fans stopped by the pits to talk to Jeremy and the team after such a dominating performance. We had a lot of fun, and are looking forward to the final round of the CA State Championship in two weeks at Willow Springs. Did somebody say lap record…
