R90/6 for hacking?

Hey All,

I have read through a number of threads and just want to double check with you all. It looks like I am going to have Bob Warks hook me up with a Velorex 562 Cruiser sidecar. Anyone have any other suggestions or comments for a sidecar? Any comments on Bob? He is only about 2 1/2 - 3 hours away from me.

Before I take the plunge I also wanted to get opinions, comments, criticisms, etc. on the bike. I have a 1975 R90/6 that I am going to add the sidecar. I assume that it has enough torque/power/hp to drive the sidecar comfortably?

I plan on beefing up the suspension both front and rear. I haven't done much research on the suspension upgrade but I will start searching the threads soon. If anyone can point me to come helpful threads I would appreciate it.

Thanks much,

good choice.

See my thread 1974 R75/6:

You will need a subframe I used a DMC front subframe and a Motovation rear frame clamp.

The 1980 and older airheads had a heavier flywheel which gives you more low end grunt (Torque) for pulling a sidecar.

You will be very happy with the BMW R90/6 little more grunt than my 750 and a high quality motorcycle for this setup. Plus I have looked at Bob Warks website and you are lucky to be close enough to have him set it up.

Keep us posted on your progress. Do you have a budgeted amount for this build???

Go for it!

I used an R80/7. It pulls hard, but the extra 100 ccs would be great!
The ladies used to check me they just keep an eye on me.

What final drive are you runnin'? Might want to consider somethnig with a higher gear ratio than the standard 11:32 (from memory... did I get it right?).
My solo bike is a '76 R90/6 with (I think) an 11:37 final drive - torquey!

I love the /6 - best damned bike they made, IMNSHO.
