Finally Found Forks
« on: 12 May 2015, 09:00:10 am »
 
After half a dozen unsuccessful bids I have finally got a set of R1 5PW forks for my front end conversion. They are gold, and black would have looked better but otherwise happy days.

Anyway, I am likely to be waiting a while for either a custom yoke set or for Devilsyam's steering stem so I am thinking of getting the forks sent off for set up. I know it would be best to wait until they are fitted but it would be great to have everything in place so I the bike is useable as soon as it is bolted together.

Has anyone running R1 forks done this? Did you need to go up or down from std springs? I have the std FZS forks set up with 9.5nm springs  and weigh about 13 st with kit.

I put some linear 10.0 springs in mine (I got std 675R springs for £10, fit in fine but needed a spacer of around 15mm IIRC ) as I used 4XV forks which have a soft spring as standard, 7.5w oil.  They are firm but you have less travel that the fazer forks and they handle 2 up riding well.

Thanks for that. I have standard 2008 RC8 springs kicking around the garage as we put the RC8R cartridge kit in mine. However, I am guessing these springs willl be in the 2002/3 R1 forks anyway, unless it transpires the forks have been upgraded in the past?

Think I will get the refreshed anyway as the oil might be 12 yrs old by now and take a view on springs once we know what is in there.
