Gen. 2 wheels in a Gen.1?
« on: 24 July 2018, 10:00:27 AM »
Sorry if this has been asked before I did try doing a search but couldn't find the answer, are the 5 spoke wheels from the Gen. 2 a direct fit on a Gen.1 bike or do they need modifying in any way, poncy I know but I prefer the look of the 5 spoke wheels.
Thanks for any help. :)

round n round lol front is easy rear bit more involved
option 1 use a custom disc which takes for ever to get made
option 2 early r6 rear caliper modded to take a tourque arm and mounted in verted

Thanks for that, getting things machined isn't a great problem as a personal friend of mine has his own engineering business so possibly easier to go with the R6 rear caliper option than a different disc, thanks for that. :)

You could take a look at my post outlining how I fit an r1 rear.  If you can get stuff machined and a small amount of tig welding it's pretty straight forward.  Plus at the end of it you have a factory looking blue spot r1 caliper, unmodified wheel/disc and no torque arm for a clean look.

Should be same as fitting a gen2 wheel essentially

I think you need to consider the disc diameter on the front wheel if you are using the Gen1 forks,  as the Gen1 Discs have 6 bolt fixing and 298mm Diameter vs 5 bolt on Gen2 and 310/320mm Diameter discs as standard. So the caliper won't be allow the larger discs of the Gen2.

Yes I was hoping to keep the original forks as personally I don't find anything wrong with them, sounds like this could get expensive! :)

Might be cheaper to buy a new bike!

I'm running 99 R1 forks and  ended up sourcing caliper spacers from a company in the US, they were fairly expensive at £170 but allows me to run 230mm disc.
I spoke a few UK companies that used to make the spacers but none were willing to machine anymore.

This is the problem with one off stuff. I found it very difficult to get any engineering firm to make up any bits I needed. They're either too busy or just not interested. I did find one firm but they're long gone now.

I'm fortunate in so much as a friend has a small engineering company so all may not be lost with the original forks, I hadn't thought of spacers, I'm just having difficulty reconciling myself with the prices people are asking for second hand wheels. :eek

There's a saying, "the best you've had is the best you know".  :)
It's very true of many things but on bikes, especially so of suspension.  Until you've ridden a Gen 1 with decent fork mods and a better shock, you have little idea of what you're missing in terms of handling, road-holding and ride quality.
Given a choice between dropping time and several hundred pounds into fitting 5-spoke wheels for cosmetic reasons versus putting that into improving the suspension, I know where my cash would go.  :)

Mike I hear where you're coming from, I fitted a BMW S1000RR rear shock to the bike not long after I got it and I find that far better than the stock one, I'm not sure if they are stock internals in the front forks but I don't have much of an issue with those I set them up how I wanted them and I've never felt that I've had a problem with them. I like the look of the 5 spoke wheels but weighing up the cost of the wheels, refurbishing them and the issues re discs I may give up on the idea as if I'm still gainfully employed this time next year I would love to go back to an Aprilia V4 Tuono.  :lol
