BOTT XR1R – featured



This is a bike we have been waiting to show for ages! When David Sánchez of BOTT Power asked us to come up with a quick CTG concept for his special track bike project we jumped at the chance. It’s always more liberating to work on one off bikes than for production models because there are way less restrictions on where you can go with the paint and graphics. Not having seen the bike in reality it was a little tricky to get the angles right and I think I would tune a couple of tiny details seeing it from all different views now, but anyway, overall David did an incredible job and we think the bike turned out brilliantly! Some superb photos too, pure motoporn!

We are hoping to try it on the track at some point, must be absolutely epic to ride with a power to weight ratio better than 1:1. The bike has more than 150 HP and a target weight of less than 150 kgs! :p

 


The BOTT XR1R is a special version of our BOTT XR1. The XR1 is a street bike, while the XR1R is a bike that we are developing to use only on the track.

We see it as a big supermoto bike, which feels “at home” on twisty tracks.

This XR1R unit is a Bottpower laboratory bike, that we are using to test and develop new solutions for our bikes and customers.

We have a very good customer who ordered us a BOTT XC1 cafe racer with titanium frame and racing electronics and one of the targets of the XR1R is to develop those components, so the BOTT XR1R has a titanium frame and also an EFI Euro4 ECU which allows to use adjustable traction control, launch control and 3 different engine maps.

I have been working for 10 years as data engineer in different championships and categories, so for us to add a data acquisition system was a mandatory step to make a good development work. With this bike we will measure things that we do not measure normally, like the stress in different points of the frame using extensometry gauges.

We have a testing program for this year with several tests on different tracks. We will also organize a test in which some journalists and some of our best customers will test the bike.

And as culmination of this project, we are working to race with the BOTT XR1R in next year 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. 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!
