SV 650 How Heavy?

[Red Herring]

Hi Folks,
My apologies if this has already been asked elsewhere but has anyone got an all up weight for a race ready SV650? Thanks.

A normal Sv is 170kg dry weight, Im Indoors reckons around 150 if you stripped it down for racing, does this help??

add about another 30 kg when wet (including full tank of fuel), i think?

Wet weight will be around 180kg I would have thought, maybe a bit less depending on fuel load. I take it this is for the thunderbikes power/weight limit? If so don't worry, you'd have to tune th nuts off it to get it anywhere near the limit.

Actually no, I compete in a Rally (special stage closed road sections) and for the past few years have been using a big supermoto bike with reasonable success. The problem now is the Aprilia SVX has come along and moved the goalposts, leaving the big singles not quite fast enough on the quick tarmac bits. I don't want to go the sports bike route that some have (very fast in the dry but a nightmare if it rains or on the gravel bits) so was exploring the possibility of building something based on the SV 650. Problem is I'm going to need to get the all up finished weight down to somewhere in the region of 150/160 kgs to stand much chance of being competative.

I once read there is an italian company making very light frames for the SV. That combined with some light wheels might save your day. I'm curious as to the weight of the SV engine. I'm thinking its a heavy little thing compared to the Aprilia SVX you're mentioning anyway. I feel that the SV might get away with a narrower tyre at the back as well. That would lighten things more and maybe work in having a more flickable machine too. Any technical guys here care to share their ideas?

The problem with the Aprilia is fragility. They are getting better but it's no good being fast if you don't last the distance. They are an awsome bike to ride though and it may be that I will have to go in that direction eventually.

If you don't want to go the sports bike route then why are you looking at the sv650? I'd have though you lose all the power advantage of a sports bike but keep all the ride height, handling and weight problems of one. The engine is a lovely piece of work if you want a narrow bike but if your looking for light weight then the Kwak ER6n engine might be lighter (parralel twin, less engine block) although a tiny bit down on power compared to the sv650.

Without a doubt the Aprilia is the pick of the bunch, however at the moment it is expensive and fragile. It is also very unstable at speed. I'm sure the Kwak may be a route worth exploring, but at the moment I'm looking at the SV because in outline it is very similar to the Aprillia with a latice frame and V twin engine. If I take just the frame and engine, and then start adding the extra bits of my choice I might just end up with something competative (and original), but I need to know what I am working towards. I guess the best place to start is getting a naked SV, taking off the headlight and rear subframe/bidywork and seeing what that weighs.....hence my original question. If a race ready SV tips the scales at much over 150kg then I'm not going to get where I want to be, even with lighter wheels etc.

So I guess your question is, "How much does the SV650 engine and stock frame weigh?"
Does anybody know?
