1986 NC21 Forks/Front wheel

[Dad]

Hope you can help, just got the bike and no pressure in the forks, what pressure should they have? Also I would like to change the front wheel for a 17" one (more tyre choice) any info, what would fit? Many thanks

8 - 11psi which will leak out over time anyway.. if the fork seals are aftermarket I wouldnt put any in there as it will just blow them to pieces in no time.

Not a great deal will fit easily, the only things that will fit without issue don't really offer any imporvement in tyre choices as you end up with odd-ball sizes like 100/80/17.

The CBR400 / NC30 wheels use a 120/60/17 which will give you a great choice of tyre but the discs won't fit as they are a different mounting pattern and they use 296mm discs instead of 276mm like the NC30 so your calipers wont work.

This should fit (CBR400 AERO) wheel. But as above it only takes 100/80/17 which will leave you with the choice of a BT45 bridgestone, or a BT45 bridgestone.

The BT45 isnt a bad tyre anyway, and you can get it in the 100/90/16 that is stock for the NC21.

After all, with the soft suspension of the NC21 I think that will give out way before a set of BT45 tyres.. I havent ridden my NC24 in a while (same size tyres as the NC21) but I used to ride the crap out of it, scraping the pegs away to nothing with BT45 tyres...
