Wanted 748 / 916 shock..
 

Hi all,

I'm current 1/4 the way through building a Air cooled, 916 frame using a 900ss swing arm.

I have modified the frame but I need to borrow a 916 shock or 749 type shock to measure the length and to do a mock-up on the bike.

I live in the Ruislip / Uxbridge area can anyone help me?

Cheers

I got myself a Showa shock from 916 not long ago, awaiting to source an Ohlins at decent price for my project (aircooled Superbike...). Won't be looking at assembling anything before the new year and now courtesy of an idiot turning across the bus lane I was travelling with, I need to fix my ST4...

I live in Purley Surrey.

You are welcome to use it if you need. I'll swap this against any tips you grab along the way of your project... ;)

Yea, more than happy to swap ideas... I'm planning to get to MD racing in the new year, so I'll let you know.

Just a few pictures on that I've had to do with the frame..

Picture 3 - Because I'm using a different swing arm I've had the cut the bottom on the frame and remove the suspension / tank to allow the shock to fit in.

OK let me know

Hmm looks like quite a lot of mods you are doing. I am going to keep the standard swingarm myself. Less aggravation I reckon, and I want to keep a single sider so I can swap wheels with the 998.

I am planning to put a DS engine in I believe but just worried about the cross member that you seem to have removed. I will have to check up on that.

Sent a PM.

Hope these pictures help.

Hi

I have a showa shock of a 748 in the garage, if you need to borrow
if your not sorted, based in Whitton.

Interesting those pictures.
I reckon that the Kyalami cross member will clear those throttle bodies... Should be good news for my project :)

Must admit if I was doing a simialr project I'd probably look at a Monster swingarm either one off a Monster S4 such as Dave (MLC Racing) has for sale or one like I have as standard in my S2R as they both use a similar shock setup to the 916

As for shocks
Standard 916 shock length is 305mm
900SS is 330mm
900SSie is 335mm

Shortest shock I have is a WP unit off a Laverda which I think is about 280mm, Can't recall what the Bimota Ohlins shock is.
To get the rear ride height correct you want to use the tool that plugs into the frame so you can take a measurement to the centre of the rear spindle

Looks like there will be a bit of work to do with the fueling
As I see a DS engine, early 270cc/min injectors and a Non Linear TPS

I know my route seems to be mad as a hatter and you are not the first person to mention about the suspension :D. My first thought was to run a linkage style swing arm or even keep with the original single sided swing arm due to my existing wheels from my other bike.

BUT I like the look of the 900ss alloy style swing arm it has clean smooth lines, doesn’t look cluttered and I was happy on a track day with a Race tuned 944ss a couple of years ago. If it doesn’t work I’ll weld all the parts back on and put a linkage style swing arm back in.

I currently have an Ohlins rear shock on my 748 race bike that I plan to use on the new bike but I do not want to take this off as I’m getting this bike ready for the track day in Portugal in Feb. I have the Ducati measuring tool so I have a Datum. But I need to make sure the shock is not hitting the side of the frame otherwise I need a remote reservoir type and they come in different lengths. I currently have a 900ssie shock but these are not so common so I need to base the length on the 305mm length.

The engine has come out a race bike that was run in Hottrax series it’s running HC Pistal pistons, polish & lightened crank and a power commander and was build by Neil at cornerspeed. However I would be interesting to talk to someone who may have played with different systems.
