550 MODIFICATION OF FUSE BOX & NEW STEERING LOCK FITMENT

(1/3) > >>

Gromitdog:
I would like to modify my fuse box from the std glass fuses to take std blade size fuses which would help to eliminate a bike thief pushing a spare glass fuse in-between the top two fuses and being able to start the bike, This is a well know problem with the fuse box on these bikes. Has anyone done this modification? If so where did you get your fuse box from & did you stick to a 6 fuse box unit ?

Also I need to fit a new steering lock to my bike as the old one had no key & the thread on the lower yoke had been mullered by pass owners,  The lower yoke I got hold of did not have a drilled hole or anything that the lock locates into or blocks so that the steering does not move / locate into, Has anyone fitted a steering lock to a lower yoke where one has not been fitted before ?





 

Bryanj:
Fuse box go to US site and message Hondaman as he does them.
Steering lock depends
500 had steering lock on bottom yoke that locked a pin against the half moon steering stop on frame.
550 had a lump on side of headstock with a Nieman lock that went into a slot cut into the steering stem, these you had to drill out if you lost the key as you could not get keys and lock was held in by a washer and rivet

This is UK models not US

SteveW:
This is what I did to mine, think the fuse box was from eBay.
My electric plate is heavily modified to allow for a solid state rectifier.

Hi Steve
That looks just about what I want to do could you give us some rough measurements of the size of it  please. I take it the starting electrical circuit is 15A on these bikes ?

Gromitdog:
Hi Bryan
Thank you for your reply can't seem to find a email for Hondaman was hoping to find something in uk that would be suitable.

I have the 550 K3 uk version and it has the lump on the headstock where the lock assy fits into the frame so I think I need the Nieman lock type , Didn't release that there where 2 types of locks for these bikes I will have a look on eBay and see what's on offer. Not so keen on drilling into the steering stem though can't afford to mess that up 😂 and would need to work out where to drill it compared o where handle bar position is to lock position .
