The Croatian VR's are clearly a low volume production, they are using general over the counter electronics heat sinks
Nothing wrong with that at all but any large scale manufacturer would have heat sinks cast up to suit
The Serbian rider who contacted me has emailed the VR Co & the reply is below
"The Croat responded (my translation, the original text below)
BMW800gs max rev speed is 9000 rpm. The only model we can offer with guarantee is 14V-3FHVSP-30A-AX. 141*88*25mm, 5 wires,
Price per unit cca 87eur, price for 2-9 units 79eur.
He has no previous experience in sending abroad, yet my experience says it is possible but would add some cost on the top (say cca 40eur) and would probably require 3-4 week delivery time for the most economical shipment option."
Considering the info above Lukas's offer to pick up a unit for testing is probably the best bet to get one quickly
