It's good to know he's human after all.

Completely open belts, even with a bit of oven grille in front? Not so much a risk as a potential disaster that could ruin a decent motor...

I’ve been through gravel traps with open belts on a 2v without problems, equally I’ve seen a friend’s 4v motor lunched after a single stray stone punched through a carbon belt cover. Flip a coin ...

I didn’t mean that, I just meant luck can be a bit random

4v do have bigger covers with a flat area at the front, but still very unlucky.

I really like the open belt look on this particular bike, showing all the Silver. Covers are going to make it look heavy and clumsy. Personally I would have made a fairly tight fitting stainless strap over the front of the front two pulleys.. like a flat mudguard if you like. With minimal visual impact.
I think there is a good argument for leaving the belts uncovered; if a stone does get under a belt it is very likely to be spat out after the first revolution and probably only go round one pulley. However a foreign object in an enclosed cover cannot escape and could be moving at speed and ping into the belts several times.. furthermore it could well go unnoticed unless it made a lot of noise and continue to deteriorate in a damaged condition, whereas open belts are immediately inspectable and any fraying or holes will come to light very soon during one of those longing looks (don't deny it ![]() emzedder had a nasty experience when his balls dropped, and his belt tensioner bearing broke up too, which is more relevant! I know that the bearings are inside the belt loop so the balls are fed into the pulleys to some extent, but I can't help thinking that many more of them might have dropped away into space if they were not enclosed. Happily emzedder is a very sensible chap and noticed the damage before a belt failure. I have a vague recollection of someone conducting a test on polyurethane drive belts, when they first started to become popular.. They were feeding gravel into a Norton or Triumph belt conversion and failed to damage the belt or pulleys, just to prove a point over chains.. Cam belt is a slightly different scenario, I agree, but I think they take more punishment than we think?

Yea, so do I and I would do exactly as you suggested for the same reason with a cowl type cover and ditch the grill. And if I can't sell these carbon covers I may do exactly that. When I've fitted my Kaemna or DP pulley kit because my stock pulleys look sh1t.

I agree that open belts are a risk.... I may look at a slightly different guard at the front as well.
For now, here is a short video of how it sounds.... I did take it up the street and the throttle response is fantastic! https://www.youtube.com/watch?v=ttwXvitwLT4 |

Oh god yeah, so many hours work in those for sure. But doesn't everyone have a CNC lathe and a 3D printer these days though?
