Axle ratio selection

[paulywombats]

Hi Monksters

I have a Honda ST1100 that's about to go through gender re assignment surgery from bike to trike.

The final ratio is 2.833, would I be correct in thinking it would be ideal suited to a Rialto mk2 axle (B)?

If unavailable at this time would 'A' axle be ok to use?

Comments very welcome.

I've got a "B" stamp diff for sale it you need one ..... the st 1100 I built ran real nice on one  2.78 is as close as you will get to matching bike it you keep wheels same size as the pan

Like Stumpy said the 2.78 is the closest you will get. but the A 3.23 should be ok the final ratio on the 1500 is 2.833
I ran a 2.78 on my gl1500 running at 70mph@3200rpm
changed it to a 3.23 now running at 70mph@3800rpm on 205x55x15 tyres

Why did you swap to 'A' axle?

Why did you swap to 'A' axle?

Where the b type is the same as the bike. I felt the revs didn't fill right for the trike with the b axle on. so swapped for the a type even though the revs went up it felt better pulling away and riding at low speeds but still has the power to pull away

Quite a bit more weight compared to the bike, make sense.

Thanks for your views Terry, very helpful on here.
