Andymann Posted February 13, 2019 Posted February 13, 2019 I just wonder if it should have a shaft drive. What are your views on that? Is it less sporty? Less efficient? There are a few disadvantages to using shaft drive - firstly being that they sap a bit of power - especially in an engine with the crankshaft running across the frame - you now have to make two 90-degree bends through a pinion gear to get the rotation to the back wheel, whereas with a chain it's all in line. Bikes like the Guzzi and the BMW GS with the crank running parallel to the frame are easier to make shaft drive but they are not out and out performance bikes. The other is that you need a double universal joint in the shaft somewhere, which also needs to be pretty strong to handle the acceleration of a bike, so they are really expensive. Shafts also have a weird tendency to "wind up" the back end of the bike during acceleration too, so you need a pivoted swingarm to counter this - the earlier Guzzis were especially bad - there was a brilliant desiger called Dr. John Ghezzi who actually patented a parallelogram swingarm with two joints to counter this. Check out the Dr. John Guzzi racers. And finally your ratio is fixed so it's not easy to just bang on a bigger or smaller sprocket to change the acceleration characteristics. The heavier weight of the crownwheel also means the rear wheel is heavier so your re-activeness of your rear suspension is also slower. So for your Touring bikes,where performance and sportbike levels of handling like FJR's, Goldwings, Super10's and GS's shaft is ideal - nice low maintenance, low wearing and very clean. But the moment you want to go sporty, chain and sprockets - simple to replace and easy to change. Wannabe and sawystertrance 2
Andymann Posted February 13, 2019 Posted February 13, 2019 There's a nice example of Kawasaki's version - but check out all the modern shafts - they all have some form of double-pivot arrangement to help with acceleration sawystertrance 1

sawystertrance Posted February 13, 2019 Posted February 13, 2019 Geez, will you look at the size of that fine print!! What a disclaimer. Haha Hairy, Grebel and Stoffel76 3
Hairy Posted February 13, 2019 Posted February 13, 2019 That old motorbike part is my biggest concern ... bloody thing is as old as me, and I am not wearing too well myself I say go for it!! (but then it's not my R10K nor my Mrs that has to be explained to why I came home with an old motorbike)
Andymann Posted February 13, 2019 Posted February 13, 2019 Just be careful - those CX's are really popular with the Beard and Craft Beer Brigade. Especially in Cape Town. If none of them have snapped it up yet, it's either because craft beer has run out in Cape Town (unlikely because I had a ****-load this weekend while watching the WTS cup race), or there is something more serious wrong with it...... sawystertrance, Steven Knoetze (sk27), Spokey and 1 other 4
Hairy Posted February 13, 2019 Posted February 13, 2019 the seller has an epic beard, but does not drink this pics show the bike to be in really good condition, but it is like a good partner in life, it should be both good on the outside and the inside ... and the inside I can't see in this case Just be careful - those CX's are really popular with the Beard and Craft Beer Brigade.

Hairy Posted February 13, 2019 Posted February 13, 2019 lol .... can't do that ... he started at 18K, then 16K and 14K a few months ago I know he is really busy with work and life, and just can't get to either selling the damned thing to anyone off the street and he is focused on his business ... so the bike is now just in the way for him, or more importantly his girlfriend! offer him R7,500-, noting missus needed Valentines treatment and you're not too sure, see if he takes the bait Ed-Zulu 1

That sounds like even more reason to chase the price down and see where it ends up. Could turn it into one of these: Wannabe, Tromp, Steven Knoetze (sk27) and 5 others 8

Sweetin the deal by sticking to 7.5k and offer him a gorilla if the repair bill doesn't run away with your budget. You really want a bike and he really wants it out of his way, win-win right there!

Hairy Posted February 13, 2019 Posted February 13, 2019 I was eyeing this build out as they took the mindset of doing as little as possible (AKA cheap as possible) That sounds like even more reason to chase the price down and see where it ends up.

Man, they're ugly in their natural state!!
