New Fork Springs Required.....

Post by robbosliding »

Hello to one and all, my first post here. I bought myself an NC29 as a bit of nostalga, never had one when I was younger, a trick little bike I missed out on so bought myself one to play on, use for 90's track days and as a commutor to save my ZX6R and ZX10R from the rain etc.
Set against these bikes and I've had alot of others both road and track the NC29 is SOOOO soft on the front end. I have put some heavier oil in the forks and reduced the air gap by 5mm to try and firm it up (the oil change was significant) however is it still very soft. The springs measure within serviceable tolerances but I would like much firmer suspension. The preload is wound into the last ring, new uprated springs I am thinking. I am told the that GF is the man here, anyone put me his way?

Were the springs you bought for worn replacement or were you after stiffer springs for a firmer front end?
Its a stiffer front end I'm after (no viagra jibes please.....) :whistle:

Yes, it made front end stiffer, but we had couple of track testing and compare with never stock motorcylce forks it is stiffer not enough. So, I have changed to CBR600RR 07 front end - for the race purpose it's ok. I have topic here and I'm 99% sure that all front end from CBR900, CBR600 will fit to our bike. Thanks Honda for this....

Looking at the Wilbour springs that Parus mentions.

Now the ebay advert says they are for a NC29 from 92 to 98 but free spring length changed from 319.7mm to 295.5mm for the R model. I emailed the seller but he is adament that they are the same size spring on all models and would be fine in my R model.

Can anyone confirm this and tell me (apart from the obvious size difference of 25mm) what i would expect if I put these slightly longer springs in if it is as I suspect.

If you need stiffer forks - you always can use longer\stronger springs and different spacer length.

I also think so, because R model has cartridge forks.
