Frame Cutting/Chopping
I want to cut the rear section of my frame so the TT2 rep seat looks better once fitted - see pic below. I know some of you guys have cut the frame for various reasons, cutting that rear section loop under the rear of the seat, is it an issue frame structure/strength wise? My guess that part of the subframe is just there for plastic tray that was there?
Anyone thoughts before i take the angle grinder to it!
thanks

Re: Frame Cutting/Chopping
That whole rear section is just to support you and your lady friend. You can take a lot of tubing out of it and still be good.
Look at some of the later model frames, and you will see a lot less frame in back, especially if you are putting on a single seat. It looks a lot like legacy ideas to me.

Re: Frame Cutting/Chopping
any metal past the swingarm pivot is to hang lights and keep your ass off the tire
Back in the day it also supported the upper shock mount, very important to keeping your ass off the ground once upon a time, ina galaxy far far away

Re: Frame Cutting/Chopping
So is it basically a 748 with a 1989 Sport engine? (which happens to be 748cc)
What is left of the Sport?

Actually it is a little bit more complicated...ducinthebay wrote:So is it basically a 748 with a 1989 Sport engine? (which happens to be 748cc)

It is an SS 1997.... with a Elefant 750 Engine, with PASO polished heads, straight cut primary, dry clutch, NCR camshafts, FCR39s, FBF HC pistons, tweaked gearbox (half from a M620) balanced and lightened crankshaft-pistons-flywheel & rockers, polished and shotpeened (primary, rods) "new profile" cam pulleys, Ignitech ignition, Dynacoils... and... I forgot what else......
The rest comes from a 748R (rear end and part of the frame), 916 (front end, shock) , 996 (wheels , now I sold the 3 spokers and got a 5 spoke version), 999 (front brakes and Mastercylinders) ; the bodywork is nearly finished and it will be a Mix of 996 (seat and tail) 1098(front cowl, & headlamp), "supertwins" race bellypan, Supersport "mezzacarena" Faring Panels and Sport "nuovo" (Tank, is VERY narrow).
I have already the dashboard made and ready with a digital speedo (chinese), idiotlights, oil pressure & temp (VDO) and Revs (the revtacho is coming from a Yamaha RD350) and Shift light, but I am not entirely happy with it, so I dont know yet if I will keep it or go for something less complicated and more contemporary.
It started as a joke and half Elefant Engine and I got carried away.

Re: Frame Cutting/Chopping
Hi Angelix,
very nice bike. Indeed you went all the way.
you finished, where I just started a long time ago.
meanwhile I collected parts such as
998R Öhlins front end incl. radial calipers
5 spoke magnesium Marchesini's
S4R swing arm (Aluminum sculputure)
changed the frame end to adapt the S4R link instead of the original cantilever.
But first I have to finish some other projects such as proper lathe to machine parts.

Re: Frame Cutting/Chopping
Hey Clive,
I'm in the eastern part of Holland app. 100 km from Amsterdam. It's small town called Holten, directly near the highway A1/E30 Amsterdam-Berlin. Visiting Assen is also my goal, probably by bike (907) together with my friend on his 750ss or 888SP3.
I heard great things about New Zealand. my son was there a couple of months as a apprentice in Invercargill on a dairy farm.
PM me if you want to meet, for instance in the weekend.
Best regards,
Bertus

Re: Frame Cutting/Chopping
Angelix - That is a most ambitious build. Awesome.
ducbertus - a lot of respect for you daring to cut the frame so far back. I'd love to see the finished product.
Has anyone else got photos of frame cut jobs? I'm considering cutting an SS frame down for a TT2 replica, and would be interested to see what has worked for others.
Thanks,
Mick
