    Hey fellas,
    So I don't own a VFR750 .. but I do own part of one. :rolleyes:

    I have a 1998 Honda CBR900RR that I bought this past August that had quite a bit of work done to it. One of which, was it had a 1996 VFR 750 Rear Swing Arm, with I guess, a VFR 800 rear wheel.

    The bike is slightly too tall for me, so I am looking to lower the bike about ~1.5inches.

    Now comes the question that has spread throughout numerous CBR / Fireblade forums, and nobody seems to know the answer, and that question is:

    What Lowering Link would I need? A set for the VFR 750, or a set for the CBR900RR?

    My guess, I need it for the VFR 750, as with the video I just took of my bike, it looks like the original spot for the mount is not in use, and it is using the parts from the VFR. BUT, you guys are the experts, so please, help me out!

    [video=youtube;amHv2eZTypQ]http://www.youtube.com/watch?v=amHv2eZTypQ[/video]

    If it is for the VFR, would this be the kit I would want?
    Hyperpro Rear Lowering Kit - VFR 750 - FREE UK DELIVERY

    I can't seem to find any USA sites who carry it, so I'll have to order it from the UK.

    Thanks a lot!
    -Kyle

    Can of worms. First you pay to raise the rear, then pay to lower it.

    Geometry is key, and needs to be graphed out before mods and after.

    One setup operates through linkage, the other not, so who knows ??

    If front-to-rear heights are changed too much she won't handle right, but it LOOKS cool, eh ??

    A 900 that has compromized handling characteristics could be a receipe for trouble.

    Thanks for the video, that was a big help. I'd say the VFR link would be the more likely choice. Have you thought about going with a shorter shock? I've done this kind of thing quite a few times with very good results. Sometimes it's easier that way. Lowering links can (and usually do) screw up the linkage ratio, shortening the shock length will not.

    Let us know how it works out for you!

    can anyone tell which shock that is in the bike? The shock top mount wasn't shown in the video. I know some of the VFR/929 shock conversions use an aftermarket bracket on the top shock mount to maintain the old shock length and maximum ride height. Is there any chance whomever did this conversion could have used a similar aftermarket upper mount bracket that can be simply shortened?

    Well, I bought the bike this way. I wasn't aware the rear end was raised due to the VFR swing arm till I talked to the ORIGINAL owner, the guy who built the bike, after the fact.

    I had a new shock put on the bike a few months ago before I put it away in storage. The guy who did put the shock on, used a CBR900RR shock. That's all I know.

    I've been looking for lowering shocks, but, it seems for the 900RR's, people just use the 98-99's anyways because they are slightly shorter.. and since I have a 98', I guess I don't have an option to go any shorter with the shock.

    That's why I'm looking at the lowering links.

    It looks like a VFR800 shock to me. They are pretty unique on the bottom side, that's how I can tell. It's probably an 800 swingarm too. That's just a guess, but since it has an 800 wheel and shock it would make sense that the swingarm is too. Probably all bought as a set.

    I have the original receipt from the guy who did all the work .. it is listed as he ordered a 96' VFR750 Swing Arm.

    I'll take pictures of the shock later, but considering it was just changed a few months ago, I'm pretty sure it's a 900RR shock.

    Does the shock have a remote reservoir? That's a dead giveaway that it's a 900 shock.

    Have you tried flipping over the triangle part? Again, hard to tell from the video, but those parts are usually not symmetric and it's possible that you could get a lower ride height by doing that.

    I think I've decided I'm probably going to go and sell the bike this Spring and get something newer. :p
