I have just had the new insurance quote - 06 Uly, age 50, clean ticket, fully comp (10 years ncd, ncd protection, £150 excess, legal, UK/EU breakdown, no pillion, no security, single bike) £175.
Had a moan at the broker (that big one we all know) and got another quote at £145. All the same but now a multi bike policy so even better. Its with the biggest UK bike Insurer so not a cheap policy.
Maybe its just my age but I have never had insurance this cheap before. At £241 a year for tax, MOT and insurance that seems good to me.
Nothing of the core of the bike has needed changing, I am still on Road Pilot 2CTs at 7000 miles, on 3rd belt but only paid for two, one set rear pads, four fronts (but thats just me), oil/filters at 2.5k, one set of front bearings so far, one running lamp, (maybe but changed them anyway) a battery/plugs and the odd OEM nut/bolt/washer etc. All the other costs have been add ons/upgrades like the Remus, FST, etc so down to me.
DIY changes of fluids, plugs, pads, filters are easy and even a belt is if you have a basic spanner head. As it goes it is also a lot easier and safer than doing a chain set IMO.
With 40 mpg in town and 55 ish on a run (95 RON) I fail to see, as yet, what the big running costs of this bike are. If the engine/gearbox goes bang then that will cost on anything (that will be £1200, for a used cam and one rocker, on your BMW car Sir) and that was an indy firm. A BMW dealer would have charged £3000 plus.
The only thing I would say is that mine has used more belts and front pads than I would have liked. I think the pads are because of the single disc, me being in town a lot and my ride style. If you were on the open road a lot and used engine braking more it would be no problem at all. With the belt I also think that it is a lot to do with town riding IE more stress on the belt via humps/extra braking etc. Both my belts broke the same. Clean and had no damage, wear or fraying which sounds like belt stress to me.
So for me its just the belt but I am ok with that because nothing is perfect. I do think "all-in-all" that the Uly in close to the best road going bike ever made. Off road is another matter. It can do it but with serious work the frame and belt would let it down. GS is best

.
So, for me, I think the Uly is the best "fun-per-£" road bike I have ever had.
