Motoguy that a seat from Motolanna. They make them specifically for the SR500 but they look great on anything. Just ordered one the other day

Motoguy; The seat is actually from DCC - Dime city cycles. Read my post on page 1 where I describe the lacking quality of the seat :(

But I'll agree, that the seat and colour options are really nice, and i love the style and look :)

Motoguy,
The materials are of a fairly good quality, and the comfort is also pretty good - at least not worse than i had expected from only 1 inch on foam padding. The problem is that the seat is not symmetrical - the font whih leans against the tank was not diagonal to the bikes centerline, so there was a gap on the right front corner of th seat. And the curved tail was not a "perfect curve" - there are small bumps in the curve. The stitching stitching is also a bit wobly, and the lines of the seat are therefore not complete straight.

I would have expected this quality from a cheap manufacturer, bu the DCC seat is 250$, and the motolanna is only 140$, so i expected the quality and finish to be the best...

Chase,
I guess that DCC copied the seat, because I had also only heard the seat mentioned as a "motolanna seat", and don't know of any who does this particular design.

Hey Motoguy,
congrats on your bike - looks sweet.
I also bought a R1 complete front end for my '83 920 , from model 2002 but is basically the same as yours only it has black inners.
Anyway, can you please measure the ground clearance from your oil pan or exhaust after the swap or maybe post a nice picture from the side.
Is it really that low so you cannot drive that thing like that?

I also have the same issue in my Gen II 1993 750. Ground clearance is just 10 cm, about 4 inches. That is not enough.

What size of tires are you using? How did you solve the going clearance issue.?

Put R1 2001 front end on my 97 xv1100 and simply cut the R1 stem in half thread and use a spacer.
No nead brushing under bottom bearing. But it's on a second gen 1100. I know first gen need one.

For sure the ground clearance is not the same as my XR650 but it's not to bad!

Looking good.... is that front tire a Pirelly MT66 Route? That is not a 120/70/17...looks like a 120/90/17, can you confirm?

Nice built

I like to built myself, so I know there are a lot off issues here.

The factories do have lots of people working to make these bikes work as well as possible, sometimes we - the riders want a different look, and looks is one thing, handling is quit a different thing, in the 60ies Yamaha brought over to Japan a retired test rider from triumph, to help with the handling of the XS650 as this is not an easy task.

I hope that your motorcycle is registered before you modify it, after you modify it, you will never get it through a safety inspection to get plates on it.

Denmark is the only country in the EU, perhaps the entire world, where modified vehicles can not go through a safety check, not even modified vehicles which have been approved in other EU countries, can be approved in Denmark, I know this, because I live here too and yes this issue is a unbelievable nightmare.

One of thousands examples was a new harley Davidson model that could not be approved in Denmark, because the front fork had a stamp that read "made in Japan" because of that, it was believed that the front fork was not original from the factory, as the motorcycle was from the US.

So before you do any more, but it back together like original from the factory, get it safety checked and get the insurance and plates on it, it is a antic vehicle anyway, so it is cheap, after that, you can change it and you will be OK, put keep the old parts, as if you ever get pulled over and the officer want more than the standard speeding ticket, he might send you to a safety inspection and you can only keep your plate, if you show up with a none modified bike, or a bike where they cannot clearly see a modification.

Have fun and good wrenching , hi from Erik

Sorry for the late reply.
I am running a rear tyre off of a Transalp mounted backwards on my R1 front rim.
Can give you dimensions later, cause the bike is not with me at the moment.
130/80-17 will do the trick too, we just didn't have such size when we swapped the front end.

Allpass wrote:Great Succes! :bg: The machine shop I used, ended up machining a new steering stem, and press fit it into the R1 bottom triple tree. They machined a lip on the stem, and a correspondant recess in the triple tree and pressed it into the triple tree from below, so it could not go all the way through the triple tree.
As i stated below - if anyone else wants to use a 2000 R1 front end, they "simply" need a steering stem that is 16mm longer, with a 8mm spacer underneath the lower All-Balls inner race. Remember to press out the stem backwards through the bottom of the triple tree.

It actually fits really nice, but i'm still thinking of extending the fork tubes - the whole front end dropped about 15cm / 4-5 inches with the R1 front end. I'm worried it might screw up the handling of the bike, but i'm also worried it might mess it up even more to extend the fork tubes, cause the angle that the tubes have against the ground will be bigger, if i don't raise the rear end as well - which i don't plan on.
Does anyone have any experience with this?

Next step is fabricating a new seat frame and making a mount to holde the rear end of the tank. I have bought a 12 cell Li-on battery from Ballistic that will be fitted underneath the seatpan, along with all the wiring and relays - i'll fit as much under the tank as possible.
After the seatframe i'll use the guide on this site, to cut out all the unnecessary wiring - i also plan on shortening most of the wires, to avoid having to curl them up - maybe i'll even make a new wiring kit myself...

Will keep you posted - let me hear your comments! :thanks:



Hello! im new to this virago page, but i was wondering something, even though this threat died years ago.
Cant you just extend the stem 8mm insted of 16? Then you dont need the 8mm spacers under the "allballs"?

I am currently in the same situation as you, and i will just put a little round aluminium "axle" in the middle of it, and well that together. it has a hole through its middle, so i think i can keep the stem pretty straight.
