This bike tips the scale at 65 kg and should loose some more weight in the future.

I wonder how it wil cope in real life but if your looking for bling this is the ultimate I guess.

The fuel tank and air filter swapped places, lots of carbon parts: wheels, handle bars, sump guard...

I have my doubts about the belt drive in regards of mud build up...

Anyone know if the rationale for belt drive is anything more than weight saving?

This bike has been about for a few years - looks like its just had a mudguard upgrade. Why go against the good points of a 4rt ie reliability by adding a load of delicate parts in the search of lightness. Engineering wise its clever but don't think its ever going to cut it for the paying public.

Belt drive would be soooo smooth. No chain to maintain, brilliant, but I think the belt guard would need extending a bit to keep our Kentish mud away from the belt.

As guys said the fuel tank and airfilter have changed position from the 4RT.

Why on earth did Montesa not take on board this type of mass centralisation during the redesign, especially as the EFI needs a pump to operate and hence the fuel tank position is independent of gravity.

This mod would at least given them something else to push as it being a new model.

id like to see me ride that thing, first rock step I came to the sump guard would be smashed into about 6 pieces!!

Really nice bike though/

if they put less stickers on bike it would be even lighter.

I think those spokes look really trick but not sure how long they`d last with me riding. I`m more off than on.

Whilst an interesting exercise, I think most posts have assumed this is not practical.

So for those riding 4RTs, what is the real weight of the bike you are riding?

Is it bolted down because it's so light it would float away ?

Nope, to give the illusion that it is so desireable that someone will want to steal it.

I've weighed mine on bathroom scales with a full gas tank and the heavy front light mounted. It has lost about 1,2 kg to a standard bike (aluminium fuel tank base plate, minimum elektrics, titanium front exhaust pipe, some carbon parts...)

It comes to 77,3 kg or 170,4 lbs

A friend's 05 4RT weighs 172lbs w/ half a tank, my 315R is 164lbs w/ half a tank. Half a tank equals about 1 qt of fuel or 1.5lbs
