Well, finally we publish photos of the BOTT XR1R. It doesn’t mean that we have finished the project, in fact we are at the very beginning.
This bike is a track version of the XR1, and we will do several track tests with it during the next months.
We see this bike as big and quite radical supermoto, which feels “at home” on twisty tracks.
This XR1R unit is a Bottpower “laboratory” bike, which we are using to test and develop new solutions for our bikes and customers.
In fact we have a very good customer who ordered us a BOTT XC1 cafe racer with titanium frame and racing electronics and the first target of this XR1R is to develop those components.
Right now the most important differences between the XR1 and the XR1R are the titanium frame and racing electronics with an EFI Euro4 ECU which allows to use adjustable traction control, launch control, 3 different engine maps and speed limiter (for the pit lane when you are in the track).
We also added a data acquisition system. Besides logging the most common channels (throttle, rpm, both wheels speed, suspensions travel, GPS position, temperatures, brake pressure, etc), we will also log some not so common information, like the stress in different points of the frame and tie rods using strain gauges. This will allow us to know how the frame is performing when the bike is on the track.
Part of the test program will consist in study the behavior differences between the steel and titanium frame.
On this XR1R we are trying also a new location for the oil radiator. The XR1 had the radiator behind the front number plate, and in the XR1R it is located in front of the engine. We will test both options on the track.
Another difference is that in the XR1R we removed the electric starter, this means that we can reduce the weight in almost 8 kilos. Of course it will be necessary to use an external starter.
After the first tests, once we have checked that everything is correct, we will organize a test in which some journalists and some of our best customers will ride the bike.
And as culmination of the project, we are already working to race with the BOTT XR1R in 2017 Pikes Peak race.
In principle we won’t be able to use the titanium frame because it is not allowed by the technical rules, so we will need to look for another solution (probably an evolution of our XR1 steel frame).
Our target with this bike in race configuration is to achieve a power to weight ratio better than 1:1. This is, more than 150 HP and less than 150 kgs.
Bottpower is a very small company with very limited resources, so in this case the first challenge for Pikes Peak will be to find the necessary sponsors and supporters to complete the budget.
As we did with our Moto2 project, we plan to explain the whole process in a very detailed way on our blog, so we invite everybody to follow us in this great adventure!
We want to thank our good friends of Husmee for their great work on the BOTT XR1R studio photo shooting.
