GPR Steering damper questions

Does anyone have pictures of the GPR damper installed on their ZX14? Also, was it pretty easy to install? Last question, what size is the steering stem nut?

Thanks.

lowcel, I don't remember the size of the stock steering stem nut, but I believe it's 32 or 34mm. I think what GPR gives you as a replacement nut is STD sizing. It was very easy to install. I had to borrow the socket to loosen the stock steering stem nut. Pics posted at url listed above.

Beautiful bike and thanks for the reply. I can't tell from the picture, does it just connect to the frame with the bolt used with the tank cover or do holes need to be drilled?

I have ridden bikes that really need a steering damper but can I ask, seriously, do you need to fit one to a bike as stable as the 14 ?

I would rather have it and not need it than to need it and not have it. To me the relatively low cost of a steering damper isn't worth dying over in case I do need it some day.

For any hard riding I would recommend it. In fact, many LSR venues require it. I agree that it is a very stable machine in stock form. But it is not nearly as stable a it will be with a good damper.

Like has been said here before, "you don't need it until you need it....and then you REALLY need it!."

Lowcel,

The frame doesn't need to be drilled. It mounts to the center nut location at the cover in front of the gas tank just behind the steering stem nut. There are two "set" screws that snug down to the frame and use RED Loctite to secure.

Thanks for all the help. I ordered one today, the non-V4 version though. With the money I saved I ordered some Puig sliders.

No...there better not be or I'll be seeking a full refund. Mine was done wiht a group that was going to the Corona Extra Honda Team...hence the gold dials.

My V4 started leaking after about 3 months of use. Returned to GPR for seal replacement...no charge and quick turn-around.

Not happy that it failed so soon but their responsiveness was good.

Received the steering damper and got it installed. Took about ten whole minutes.

I think it was a 32mm, or you can use a 1-1/4" socket which is what i used. It was on pretty tight so make sure you hold the bike tight and use a long breaker bar.

Its actually quite shocking how a machine with such a steep rake is so stable in factory form. 23.5 deg rake is pretty darn steep for any bike, let alone one with a near 50:50 weight dist. My gixxer 750 doesn't even have a rake that steep and that mofo gets squirrelly sometimes wheeling it around the canyons.

I appreciate the advice but I got rid of my ZX14 about a year ago. I decided to try out a different type bike.

Nope, mine is a 2007 (I purchased it new as a left over), it was produced before Harley acquired MV Agusta.

Thank you, I certainly enjoy it. There are some things about it that I like better than the 14, some aspects of the 14 I liked better than the MV Agusta. I still believe that the 14 is a truly awesome piece of machinery, it just wasn't exactly what I wanted.

The GPR V4 is the later version of the one pictured above and it seems to be smaller. I have the V4 and its been great, No key interference at all.

You didn't install the other 2 screws to the frame? I had to drill 2 holes for my Scotts damper to ensure its sturdy.

GPR does not come with or require that you drill holes in the frame, mount seems plenty solid
