Title: CB400 BHP
Post by: Andy1976 on June 25, 2009, 09:38:50 AM: Hi all, does anyone know the bhp for the 400/4? My wife is doing her bike test but when she passes she's restricted to 33bhp for 2yrs.
We're looking for her next bike snd she likes the 400.

Cheers
Andy.

I recall someone else asking this a while ago - I think they went to a dealer/mechanic and got a letter stating that a 30+ year old bike would no longer make anything like the manufacturers claimed output at the time of sale!

Try it - you never know.

It goes fast, fast.... :o

They specifically mentioned the 400/4 as one of the bikes that would be appropriate to use on that type of licence.

If you look carefully it does say 37bhp.I would think that Honda UK would be contacted in the case of any court case and a similar page produced as evidence.

There are restrictor kits available to reduce down to 33bhp which then come with a certificate guaranteeing this.

Post by: andy120t on December 15, 2009, 02:59:00 PM: Given that it's an old bike and probably sub-33bhp already, you might ask them to guarantee it makes 33bhp with the restrictor kit! :)
