When Hitchcock came out with their 462cc “Big Bore Kit” that needed the Powertronic on top for a bit more torque and HP I though it outrageous to ask the purchasing price for a good used Himalayan here in India, namely over 1000 Euros, for this enhancement.

Now, Mr. H & Co certainly have a reputation, both for quality and exorbitant prices. If you are rich and do not care about money, then they are probably a good choice.

Then I came across a lone motorcycle aficionado from Italy who runs a tiny operation selling stuff – not unlike me. After crossing the roughness of the language barrier we agreed to cooperate. While he profits from my supply of original RE cylinders I get his Italian made pistons with rings and all for his production price, which is still quite high because each one is made to order individually.
I do trust in Indian cylinder boring. It has been done for many decades and in the millions. Its proven quality by now. Add to that a high standard Italian piston and you get 450cc upgrade assembly considerably less pricey than the British variant.

If you have a carburated bike you need not change anything, the UCD33 carb is good for this upgrade without any configuration changes or re-jetting.

If you have an EFI bike a simple fuel flow control unit that is manually operated can be purchased along with the 450cc set, it is much simpler than the Powertronic and comes at 60.- Euro. But you can also use the Powertronic instead.

The cylinder wall after boring and honing remains very thick and stable:

The Italians, who already have a few EFI bikes running with 450cc, report flawless operation with quite tangible improvement of the torque at low RPM, just what the doctor ordered for this slightly under-powered bike.

Expect sales to start not before August 2020 due to Corona lockdown and quite possibly later.
