Billythekidd Posted January 28, 2019 Posted January 28, 2019 Want some advice on what alloy to use for bracing up my 750 frame and what feedback anyone has on how different their bike feels with what bracing they've done? Quote

Why do you feel the need to brace it? I asked the same question before about bracing mine. got no definitive answer. I decided not to bother as it only adds weight. once I sorted the forks and shimed the engine mounts properly. It now handles really nicely even on slicks. I am still curious to know what difference it makes. Edited January 28, 2019 by dupersunc Quote
Billythekidd Posted January 28, 2019 Author Posted January 28, 2019 Only that I'm putting a 1052 motor in and wanted a bit of extra rigidity to cope with any extra power, to be honest Dunc, I've always found the handling pretty spot on but wasn't sure if the motor ends up tuned etc the frame might struggle to cope with the extra grunt.

Ben Slabby Posted January 28, 2019 Posted January 28, 2019 @clivegtohas a slabby 750 frame with a motor pushing over 250 ponies. I think his frame only has the area in the headstock casting braced. I'll find a pic... Quote

Ben Slabby Posted January 28, 2019 Posted January 28, 2019 How functional it is, I don't know. I'm sure he'll be along shortly... Quote
Dezza Posted January 28, 2019 Posted January 28, 2019 Clive's frame is also braced on the inside in the hollowed out well sections of the stock frame near the swingarm pivot. He showed me this at the recent Newark show 1 Quote
Ben Slabby Posted January 28, 2019 Posted January 28, 2019 Actually yeah... that rings a bell now. Quote
clivegto Posted January 28, 2019 Posted January 28, 2019 I call it the Turbo Scratcher handles like a dream makes 260hp. Head stock is braced, big cross brace on frame under the back of the tank & braced on the inside of the frame around the swinging arm pivot also has subframe raised by 50mm, frame mods were done by NWS back in the day. Think it was a endurance race frame in a former life. This bike holds its own with any modern super bike, it's just me that's getting a bit old lol. 6 Quote

Mine has an 1127 with cams a flatslides. Hard on the gas in 2nd and 3rd it squirms about a bit, but that's the swingarm flexing, traction is brilliant though. That said i got hit up the arse by an R1 on track last month and something on the frame or swingarm has broken. I haven't had a chance to strip the bike to find out what has failed. I'll report back when I do. 1 Quote

Yeah I've got an 1100 J but it's on the road and my only road bike at the moment so I'm reluctant to borrow the frame, the 11 frames are commanding more and more money that's the problem. Quote
Leblowski Posted January 29, 2019 Posted January 29, 2019 I did the whole yoshi bracing on my 750 including the swingarm brace, cant tell how the frame performed before cause i started racing after the bracing. I only can say that the bike is performing really good. You can find some pictures in my topic. Quist Racing sells the kit’s to perform this bracing wich is based on the kit i made and used on my bike. Quote
