Belt Drive Conversion

Today i had the FreeSpirits belt drive conversion installed.
My mechanic likes a good ol´ challenge and is always up for some modding. Luckily for him this mod didn't disappoint !
***This conversion SHOULD be done by a pro.

The sensation of a belt drive is very different to that of a chain on the Bobber. I feel that throttle control is now more 'electric' and power is delivered to the back wheel with less of a delay & in a mature yet potent manner. There is certainly NO indication of any power loss. If anthing, the bikes feels EASIER to accelerate with from first gear onwards. Its hard to explain, but the best way to put it is that both on and off the throttle, the bike is smoother and therefore feels faster.
There is definitely less noise and its fun to hear the gears clicking into place perfectly with every shift.

Overall, its a very special mod and i think it compliments the Bobber perfectly both in looks and functionality.

And here is the front brake upgrade.
So far i cannot comment on the new front brake, as bedding in requires a few KM of gentle input. I´ll report back after i´ve covered 150 more km´s or so...

Nicely done! Are you able to explain why it was a difficult install?

Only that it invloves cutting.
Like i said, my mechanic is amazing and loves every kind of work on cars/bikes.
He said the kit is VERY well made and everything fits precisely. BUT it wasn´t easy.
He gave it an 8/10 on the difficulty scale, as tools and knowledge (& experience/confidence) are needed.

Sorry i can´t be more specific as i was not there while he worked on my bike. It took him a whole day from start to finish.

I wonder if cutting will be required if you had to replace the drive chain? The mod is definitely worth it though.

I don't think you would have to cut anything for OEM/chain replacements. But i´m not 100% sure.
Either way, the belt conversion has been designed so you can always revert back to stock.

Here is the instruction manual in case you want to see how its done:

of all the modifications available on this bike, this one seems by far the most controversial....and yet the most intriguing to me. Thanks for the report!

I would love to have belt drive. This is my first bike in many many years with a chain. BUT all of the disassembly would be required every time the belt is replaced and I don't know if it is worth that expense.

How often do belts need to be replaced though?

Belts can last a VERY long time (between 50-100k+ miles) depending on usage.
Pulleys also have to be replaced from time to time, i think.
I suppose there is more labour involved when the time comes to replace it (when comparing to chain).
