Type 7.1 Race-Kit engine. racing gearbox

This is an engine specifically engineered for short circuit racing and complies with the current FIM SBK-, JSB-, BSB SBK-regulations.
The type 7.1 specification is the purchasable derivative of the engines used in the BMW Motorrad WorldSBK Team and includes additional, regulation-conform performance parts. Due to the usage of these performance components, there is an increase of production and rebuild expenses. Furthermore, the higher mechanical strain that comes alongside maximum power density, causes maximum mileage to be reduced.

Production
All engines – for private customers up until the BMW Motorrad WorldSBK Team – are built and tested by the BMW Motorrad specialists of the engine and dyno technology center the so called “MPZ”, in Berlin.
All parts and engines get a huge quality benefit since this department produces the stock development engines and takes care of the stock engine production quality management in the plant.
This means,they have access to all required stock production parts and pick the most suitable parts for their specific Race-kit engines.
All these engines are completely hand built and documented – only the best is released to the customers. So far, the MPZ produced over 100 Race-kit engines per year for the S 1000 RR.

Which specific handling process do the Race-kit engines get?
Before and during assembly a large number of parts are measured and documented.
After assembly, the engine is run in on the dyno, followed by three performance tests. Only if the targeted performance level is achieved, the engines will be inspected, serviced and finally sealed, before they are prepared for delivery. The engines can directly go on racetrack, no more running-in by the customer is necessary.

What distinguishes the Race-kit engines from the production engines?
There are different specifications of engines based on international motorsports regulations. Due to this fact, the baseline is an engine with specially selected (handpicked) stock parts like conrod, piston and crankshaft. Moreover, there are engine specifications available featuring components engineered to combine maximum performance and compliance to regulations for other championships such as WSBK.

Type 7.1 Race-kit engine:

Gearbox:
Building on both race experiences gained in various championships over many years and thorough data analysis in terms of optimum performance, BMW Motorrad Motorsport developed the new “MS02” gearbox and amended the layout of the gear ratios completely (shown in red) compared to STK (see picture 02).
This layout is specially designed for the M 1000 RR engine characteristic and ensures a smooth transition during shift. Combined, the effective tractive force at the rear wheel increases significantly in the higher gears, compared to the previous “MS01”.
This component is permitted by FIM WSBK regulations and suits to most common short circuits.

Exhaust:
The exhaust is not included.
Conditioned by the successful cooperation together with our partner Akrapovič in terms of power development, we clearly recommend using a suitable system for the M 1000 RR made by Akrapovič. The exhaust system can be found in the Accessories tab.

Airbox:
Standard airbox with optimized upper and lower trumpets designed specifically for this engine.

Camshafts and valve train:
Performance inlet and exhaust camshaft with optimized valve spring package.

Motorsport ECU and electronics package:
BMW Motorrad Motorsport has developed the M Race Calibration Kit. This package includes distinctive features such as extended electronic adjustability thanks to the new M Race Calibration Software as well as MoTeC-solutions for data-logging and dashboard. Those electronics were developed to comply with FIM regulations and can be found in the Accessories tab.

Mileage till rebuilt:
The recommended mileage till rebuilt is max. 2.500 km.

Power and torque:
All engines are performance tested on the accurate BMW Motorrad MPZ development engine dyno.
The type 7 engine reach the following performance at the crankshaft (ECE-performance reduction):
Power: 169 kW at 14500 rpm (+/- 1kW)
Torque: 123 Nm at 11250 rpm (+/- 1Nm)
Note: we explicitly and only refer to the dyno figures from the MPZ.
