GPX250 Tail

Cam229 · Post by **Cam229** » Fri Mar 17, 2006 9:27 pm

I'm thinking of removing the ugly mudguard off my 88 GPX250 to try and tidy it up a bit.

I have seen the clean lines of the GPZ tail, and was wondering if anyone had tried to fit a GPZ tail tothe GPX?

All comments will be appreciated.

I was looking at doing this too, was told you can get indicators to fit beside the tail light.. Let me know how ya go

Well my old bike was a gpx 250 and it was a jap import. Next to the tail light were blacked out indicator's, so yes you can connect them, i tried but couldn't get the paint off them. Ask around the wrecker's.

Also, visit ninja250.net where a number of people have made the fender elimination and integrated turn signal mod's. Check out their FAQs section and look in the mods section.

There was a ninja250 member living in Japan who used to organise sending the amber lenses from wrecked Jap-spec GPX250s, which replace the black plastic panels in the Aussie spec GPX250s, so you could do away with the indicator stalks. (Of course this makes your bike technically unroadworthy, so maybe hang on to all the bits for when it's time to sell, just in case).

The other possibility is that the US-spec Ninja 250 has red lenses instead of the black panels, some of the yanks put additional brake light bulbs in there (so three bulbs light up when you brake, instead of one).

As far as putting a GPZ tail onto the back of a GPX, anything's technically possible, but how much effort are you going to go to (it's not going to be a straight swap, just like you can't bolt ZZR250 fairing onto a GPX250 without some very ugly rough edges showing). Did you know the red seat on the GPZ250R is also renowned for rubbing red pigment off onto the bum of the rider?

i used thinners and it worked perefectly.

Most GPX's I've seen (the Australian delivered, non grey import ones anyway) have solid black plastic panels (slowly fading to grey), not black painted lenses.

However, if your GPX does have a coloured lens with black paint on it, apparently oven cleaner works a treat. Also, brake fluid apparently does a good job as well.

This I know from other ZZR250 riders who've put the indicators back into the rear fairing after stripping the paint off the indicator lens panels.

I wasn't planning on using the side lights of the tail, as the ones on my bike are red.

I was going to get some mini LED indicators and attach them to the eliminator.

I have looked at the ninja250 web site and got a few good ideas from there.

I'll send photos when (and if) I complete the mods.

Hey guys, sorry to bring this thread up from the dead.

My GPX is jap spec (well its ass is, it only has 1 front disc).

I ready you guys sayin that its not roadworthy, to have the indicators alongside the brake lamp. But from Federal Register of Legislative Instruments F2005L04012
Australian Design Rule 19/02 Installation of Lighting and Light Signalling Devices on
L-Group Vehicles
Appendix A – UNECE R53
17

For rear indicators, the clearance between the inner edges of the two
illuminating surfaces shall be at least 180 mm on the condition that the
prescriptions of paragraph 2.11. are applied even when the registration
plate is mounted;

paragraph 2.11 says

“Angles of geometric visibility” means the angles which determine the
field of the minimum solid angle in which the apparent surface of the
lamp must be visible. That field of the solid angle is determined by the

segments of the sphere of which the centre coincides with the centre of
reference of the lamp and the equator is parallel with the ground. These
segments are determined in relation to the axis of reference. The
horizontal angles beta, correspond to the longitude and the vertical angles
alpha to the latitude. There must be no obstacle on the inside of the
angles of geometric visibility to the propagation of light from any part of
the apparent surface of the lamp observed from infinity. If measurements
are taken closer to the lamp, the direction of observation must be shifted
parallel to achieve the same accuracy.
On the inside of the angles of geometric visibility no account is taken of
obstacles, if they were already presented when the lamp was typeapproved.
If, when the lamp is installed, any part of the apparent surface of the
lamp is hidden by any further parts of the vehicle, proof shall be
furnished that the part of the lamp not hidden by obstacles still conforms
to the photometric values prescribed for the approval of the device as an
optical unit (see annex 3 of this Regulation). Nevertheless, when the
vertical angle of geometric visibility below the horizontal may be
reduced to 5 degrees (lamp at less than 750 mm above the ground) the
photometric field of measurements of the installed optical unit may be
reduced to 5 degrees below the horizontal;

Can someone explain the last paragraph? Makes no sense.

According to my mate, the indicators are 182mm appart and meet the initial criteria.

Thanks heaps
Ben
