Fastest BMW in Bolivia
« on: August 13, 2018, 08:24:19 am »
Found this on my computer news time line the other day.  The news isn’t that amazing as the stock s1000RR is good for almost 200 mph right off the show room floor.  But the 360 degree video of the qualifying run is pretty cool letting you swivel the view around as its playing.  Retrieved at: https://www.msn.com/en-us/autos/motorcycles/this-bmw-s1000rr-just-broke-the-record-for-fastest-bmw-motorcycle-at-242-mph/ar-BBLpKHQ?ocid=spartandhp

This BMW S1000RR Just Broke the Record For Fastest BMW Motorcycle at 242 MPH

Eric Brandt 8/2/2018


After a rather dramatic experience at Mike Cook’s Top Speed Shootout in Bolivia, the Hunter Sills Racing team is walking away with an official speed record (pending FIM ratification) and an unofficial speed record.

The HSR team broke the record for fastest speed achieved on a 1,000cc naturally aspirated four-cylinder partially streamlined motorcycle (very specific, yes, but still impressive) at 229 miles per hour. The same team hit 242 mph on its modified BMW S1000RR making it the fastest recorded speed ever for a BMW motorcycle. The bike was piloted by Erin Sills who broke her late husband Andy Sills' record of 221 mph at the Bonneville Salt Flats back in 2013.

The same team hit 242 mph on its modified BMW S1000RR making it the fastest recorded speed ever for a BMW motorcycle. The bike was piloted by Erin Sills who broke her late husband Andy Sills' record of 221 mph at the Bonneville Salt Flats back in 2013.

The HSR crew was able to swap out the blown engine with a spare, making the final day of the challenge the only day the team was able to make any serious speed record attempts. It was Sills’ qualifying run where she hit 242 mph but she ran into another electrical issue which prevented her from securing that record officially with a second run. In the final hour of the meet, Sills managed to get an official speed of 229 mph and backed it up with another 229 mph effort.

So the more impressive 242 mph mark stands as the fastest speed ever recorded for a BMW motorcycle but unfortunately won’t go in the FIM record books since it couldn’t be backed up with a second run. However, 229 mph is still impressive and good enough for a record in its category. You can watch Sills' 237 mph qualifying run below.

It's a testament to the efficiency of modern production superbikes that even when modified and in ideal conditions, they aren't that much faster.

Oops....not that ideal at all.  Running at an altitude of 12,016 ft according to the info on the video clip that engine is giving up a awful lot of power by not being supercharged in some way.  The rule of thumb is that normally aspirated IC engines lose 3% power for ever 1000 ft of altitude above sea level.  So, at 12016 ft that engine is producing 36% less power than the same engine would make at sea level. 

Now imagine how fast that bike would be at the Bonneville Salt Flats (4219 ft.)!

I guess I was misled by this bit: "The HSR team broke the record for fastest speed achieved on a 1,000cc naturally aspirated four-cylinder partially streamlined motorcycle (very specific, yes, but still impressive) at 229 miles per hour. The same team hit 242 mph on its modified BMW S1000RR making it the fastest recorded speed ever for a BMW motorcycle.

Paul, that's brilliant!  Your day could go like this:


Ride to breakfast = 15 minutes (10 miles)

Have breakfast...linger over coffee...read the paper = 60 minutes (0 miles)

Ride to course = 20 minutes (15 miles)

Blast down the course, turn around,  blast back  = 10 minutes (30 miles)

Consult time slip...discuss with crew...refuel and try again =  5 minutes  (0 miles)

Blast down the course, turn around,  blast back  = 10 minutes (30 miles)

Consult time slip...discuss with crew...refuel and try again =  5 minutes  (0 miles)

Blast down the course, turn around,  blast back  = 10 minutes (30 miles)

Consult time slip...discuss with crew...refuel and try again =  5 minutes  (0 miles)

Blast down the course, turn around,  blast back  = 10 minutes (30 miles)

Consult time slip...discuss with crew...take a siesta...refuel and try again =  25 minutes  (0 miles)

Blast down the course, turn around,  blast back  = 10 minutes (30 miles)

Consult time slip...celebrate new record with crew =  10 minutes  (0 miles)

Ride home = 25 minutes (20 miles)


Make it home for lunch in 3 hrs and 40 minutes after covering 195 miles AND setting a new record.
