Would love to know your thoughts on it, especially from a street riding viewpoint
Thanks for that z00. Yeah i definitely don't want to increase the wheelbase so I'd either remove a link or get a shorter chain.I did a 520 conversion with -1 in front. Acceleration is great. I still hit 186mph. Keep in mind I'm ~185lbs with gear. I have a sprint filter and a Racefit slipon, IAT relocation mod (really like this mod).
Other riders with RR 15+ go crazy wondering why I can pull away faster than them.
My only issue with 520 conversion is the chain, when you do -1, chain becomes longer. So my wheelbase is about 2cm longer now. It's good for stability and reduces wheelies coming out of turns. But it makes turn in harder. @d40 has the same chain I have. He removed another link from it, his system has a ~1cm shorter wheelbase. Not sure if his bike wheelies more or not. But it would turn in faster.
Bottom line I do would 520 conversion, -1 in front. I went with Alpha sprockets, and DID gold ZVMX 120 link chain. You might want to remove a link from it depending how you like your wheel base. I think I'm going to remove one from mine. I prefer a shorter wheelbase.
DID 520 chain is about 3lbs lighter than OEM one. Sprockets are also lighters (did not weigh them). But noticeable when holding one in each hand.
I have gone -1 on my 15rr and have found it lengthens the wheelbase by approximately 7mm. which is coincidently one length on the swingarm adjuster lines. (line to line)
I have just now ordered a rear 46T 525 to fit the HP wheels from Alpha racing in Germany. This extra tooth in the rear +1 from the OEM 45T should bring me back to approximately the stock wheelbase setting.
As the -1 alone makes the 15rr turn in like a Pig, and is basically a **** feeling for fine control.
Someone on this thread mentioned that going -1 up front created about a 2cm increase in the wheelbase from stock. I believe this may be incorrect and am now worried that my workings out for the increase was incorrect.
Could someone on here with a bigger brain please correct me or the other guy.
-1 up front on a 15rr is worth about 7mm in wheelbase increase from stock... is this correct or incorrect.?....
Some of you guys on here are pure genius.
going -1 up front and +1 in the rear with the stock chain, to me should equate to almost the same wheelbase length as stock...RIGHT.... hope I'm right.
I think we are all confused as there does not seem to be a answer yet.
I will know when that rear arrives.
