Reduced power output

A small step for man, a giant leap for the Bombus  K75.
Passed easy both reg inspection for 35kW and annual tech inspection without any issues.


The Official Power reduction to 35kW my friend Thomas helped me with as a authorized dyno operator for this certificate .
But before we started to fiddle with the power reduction we tested the full power output.



About 59 hp on the rear wheel correlates quite good with the stated 75hp on the crank back in 1992.


Just put a 5mm spacer between the airbox and the throttle linkage to achieve the 35kW.


So now it have 35kW on the crank and will be legal to drive even for younger generations.
So I think now I have worlds only K75 with 35kW.




In Sweden there are three levels of motorcycle licence.
A1, 16 years: max 125cc and 11kW
A2, 18 years: max 35kW
A, 24 years: unlimited
(You can also get the A licence two years after passing the lower A2 level.)

Next up, much ridin´and some wrenchin.
Wrenchin´gonna result in a small flyscreen of alu over the headlight.

Kaferacer

A new era has begun for Bombus Speedshop, the BMW era.
Finally I have K75 that I've wanted for so long.

Feast your eyes on this ridiculously over dressed but immaculate thing from the nineties in "Classic Black Metallic" Color Scheme. But it´s not really black, more like very, very dark green metallic
But feast on it NOW, because very soon this new project gonna be stripped and agile like never before.
Originally a K75S  from 1992 with Pichler fairing and BMW bags, Peltor intercom, Panasonic cassette player and Secar alarm system.
It have just 32000km/19900 miles on the clock, almost not broken in if you talk BMW language.
Those machines are normally +150000km/100000 miles at this age.

First up, stripping bags, fairing and electronics.
Next up, 7" headlamp and general maintenance.

The very big second thing that made me bought this, my son wants to take his motorcycle licence.
And because his young age the power limit is 35kW so a decrease in power must be taken care of and then to be certified by the technical inspection.
35kW might sound like little but its almost 50hp in a 200 kg bike.
That's just a little less then what i have in the Sportster build and that one roars like hell.
