VFR750 RC24 6X

Reading the rules before attempting to follow them is just boring so let us get stuck into some hard thinking and work to sort the swing arm out on the VFR. I had a small dilemma with my VFR750 RC24 6x [rep] build: The swing arm didn't look much like what it was pretending to be. The caliper was all wrong and on the wrong side of the swing arm which itself was the wrong shape and looking no better for it. Changing the swingarm was going to be a lot of work but, conversely, modifying the original for racing then upgrading again later would be a great way of throwing money away so I decided to try and find something more suitable looking. ** Spoilers** I ended up not carrying out the swing arm swap due to not being able to for CRMC eligibility. I am going to leave the process in here however for anyone else trying to do this to their own machine so they can have an idea of what will be required to achieve such a swing rm upgrade. If you're not bothered about this, then...

The chain and sprocket set was old and mismatched. it was time for a replacement but off the shelf was just not going to cut it. The stock VFR750 FG chain is a 530 pitch which is great for racking up miles with the odd lube when you get the chance to but I was racing and that chain was going to be bulky to lug about. Finding a replacement chain at a more suitable weight would be tricky enough but I was now running a CBR600 F3 rear wheel  which ran a 525 pitch chain to add a little complication. I wanted to run a 520 gauge chain (the RC30 ran one so it will be plenty strong enough for the RC24)  which is a lot lighter weight and would offer less rolling resistance over stock. This has been done by other people by buying kits that featured "special made to measure" sprockets and came with an associated price tag. Now I knew that the splines on the output shaft of my engine and the bolt spacing on the rear sprocket would be common to other machines and many o them run a...

You already know what's coming but I can promise you this will be 'wheely' good...  If you read the previous blog entry about slotting the CBR600 F3 front end on: you will have already seen the above image giving you the shocking sneak preview that I intended to fit a CBR600 F3 rear wheel to the VFR750 too! The 18" OEM wheel shares the same spindle size, making this mod fairly easy. This was dropped out and sold on then slotted into the back of the VFR. It is very nearly as simple as that. The chain lines up nicely with the original left spacer leaving only the right side spacing and the rear brake caliper to sort for a really straight forward mod. Of course it could not be that simple and straight forward or the forums wouldn't be full of unanswered questions and half assed descriptions of other peoples solutions. The back brake The simplest answer is to reduce the size of the VFR's caliper bracket so it can line up with the CBR600 wheels smaller di...
