    VFR750 weight reduction and more

    Got a VFR and associated parts bike, great bike, and I'll be doing a 'stock' mod build to keep it touring oriented, so not like the cylonbros. Start with a lot of weight reduction, its a bit heavier than it should be imo. Ali subframe, fairing frame, etc etc. Will track down some decent scales too so I can track the weight losses...

    Here's some pics. Was trying to check the compression on the parts bike and found the sprag clutch is a bit fucked, welded that up and tested, got 140 to 60 psi, so needs a rebuild on that one. At least it is a roller now, and taking up far less shed space.

    Heaviest part of those is the motor. It also lends a lot of stiffness to the frame which is a bit limp anyway. You can chip away around the edges but if you get into the frame seriously it won't be happy...

    That mass of exhaust looks like it could do with a diet.

    You could save weight by buying one of Ed's batteries.

    Or mount the battery lower in the frame which is what Im doing on my girls CBR to get the weight lower. Along with all the electrical do dads.

    Nice bike, I shall watch with interest.

    Yeh sure could, and there are a number of steel heat shield plates associated with that design too which could knock off another kg perhaps.

    Save more by getting two of Liams

    Lose some weight fatty!

    Full fluids weight just cracking 250kg. Well, there's certainly room for improvement anyway...

    Also, battery is pretty fucked, so first kg saved will be from replacing that with an UB I think.

    You got a source for motor rebuild kit?

    What you need a wheel for? what is wrong with your one?

    Motor rebuild kit??...no idea, I just bought a spare engine with half the k's

    Rear wheel?...96 has a 5inch, 93 5.5...better range of tyre choices with the 5.5 (And they look better with the 8 spoke instead of 5 )

    I see, well I do have a spare '90 wheel (same as the 93 I'm pretty sure) but the trouble is it is holding up a whole bike's worth of other spare parts, so it would have to be a fairly good offer to get me to part with it...

    ...gimmie a yell if your keen on shifting it mate (No rush...cos I is broke as fuck after buying our first home )
