BOTT XC1 cafe racer


BOTT XC1 cafe racer

The Bott XC1 is a sportbike with cafe racer aesthetics built around a Buell XB12 donor bike.
The bike weights 179 kgs (20 kgs less than a Buell XB12 SS) and has 100 HP with lots of torque. Apart of the top fueltank, it has a secondary fueltank under the rear shock absorber, which allows a total fuel capacity of 13 liters (not bad!).

The cafe racer shares the frame, secondary tanks, wheels, swingarm, suspensions, wheels and brakes with the BOTT XR1. This means that if you have a XR1 kit, it is possible to convert it into a cafe racer just changing the subframe, seat, tank, handlebar and headlight. And vice versa, if you have a cafe racer you can convert it into a XR1 quite easily.

The chassis has been designed and built keeping the original Buell XB geometry, so it has the same behavior, improved by the weight reduction.
Frame stiffness has been calculated using Finite Element Analysis, and the design has been validated testing the bike on circuits with professional riders.

We can build a complete XC1 cafe racer for you. We also sell a kit, so you can build your own unit if you want. We sell each part of the kit separately, so you can buy only those parts you are really interested in, and build your custom XC1, at your own taste.

PROJECT MILESTONES

These are the main milestones of the BOTT XC1 cafe racer till now.

The cafe racer project was launched on January 2014.

We showed the cafe racer version one in March 2014.

We showed the cafe racer version two in July 2014.

And cafe racer version 3 in August 2014.

In September 2014, the first prototype was on its wheels.

In September 2014, we showed the advanced electronics we are developing for both the BOTT XR1 and the XC1 cafe racer. This will be another option.

In October 2014 we showed the cafe racer version 3b.

In December 2015, we had ready the CNC machined mockup for building the seat/tail in autoclave.

In May 2015, we showed a front fairing design for the cafe racer, that will be another option once we have it produced.

In July 2015, we showed the new titanium frame we are developing as another option for both the BOTT XR1 and the XC1 cafe racer.

In October 2015, we had ready some special parts (carbon fiber tank and seat).

In November 2015, the first prototype was finished, and the BOTT XC1 cafe racer was launched to the media.
