Lotsa good info there Kyo. And good to see some 'cons' to all those 'pros' being touted. I had a mini-bike when I was a small kid so I feel I've satisfied my rekluse curiosity.

I have a viable running '85 VF700S Sabre in my garage Probably the same stator, wow.

The following information is combined Tech form different threads and my own head...

This information can be used to build a wide ratio or close ratio gear box for all of your needs.

The primary and final gear ratios only effect the effective overall ratio. They don't change the transmission ratios You'll need to split the cases for that.


Stock gear ratios

XL600R

Primary Reduction 2.188 (70/32)

1st Gear '83-84 is 13/32 (2.46)

1st gear '85-87 is 13/31 (2.38)

'85-'87 XR600R & XL600R

31/13 2.38
28/17 1.65

XR 5th gear 21/25

NX 5th gear 20/25

Try some combo's on http://www.gearingcommander.com/ for a while.

You can change the listed NX650 5th gear tooth count to the Euro spec.

I used that same chart and elaborated with different primary and final drive ratios back when I was trying to decide what gearing I wanted to run.

I am wanting to create a wide ratio gearing for my XR650L and trying to learn if there is a Honda OEM stock first gear from any Honda 650 engine that is compatible with the XR650L that is one tooth more than the XR650L stock 1st gear.

What I'm trying to do is get the ratio to something like 33/12 - 2.75 or 32/11 - 2.91. I'm researching if there exists a gear or gear pairing that will accomplish this.

Is there a compatible Honda 650 transmission that would drop into the XR650L transmission and give me the gearing ratio preferably close to a 32/11 - 2.91?

I have already obtained the 2nd and 5th gear listed on this thread.
http://www.advrider....ad.php?t=649249

My thought is if I am going to crack the case open then I might as well get all the gearing I want.

Any help would be greatly appreciated.

The 1st gear is #4 on the parts fiche.

Here are a couple spreadsheets that show the differences in the 2nd and 5th gear swaps

XRL with stock gearing and stock 15T/45T sprockets


XRL with NX650 gearing but still with stock 15T/45T sprockets


XRL with NX650 gearing but still with 15T/48T sprockets


XRL with NX650 gearing with 14T/49T sprockets



Here is a link to the program above in case you want to plug some values in for yourself.

I only changed the 20T 5th gear to a 21T and I changed the 17T 2nd gear to a 16T. The gears are direct drop. You only have to change one gear where there is only one gear that is different in the pair as marked below. The gears on the NX650 have one tooth less that are in bold below. The reason why the the gears in bold below are direct drop in is because the actual teeth on the NX650 gears are thicker to compensate for the smaller gear diameter. I changed both and they are direct drop in trust me. Keep in mind that if you frig with the other gears you might have to change the pair (drive and driven) in order to change the ratio. If your going to change the ratio of any gears where both tooth count on both gears in the pair are different then you'll have to change the pair of gears.

i.e.
------ NX650 ... XRL650
2nd--- 28/16 ... 28/17
5th--- 20/25 ... 21/25


I assume you mean there is no ratio higher than 2.66, if so than you are correct 2.66 is the highest ratio available but by putting a NX650 5th gear you can change the sprockets to raise the final ratio higher but keeping the final ratio in 5th gear reasonable for highway use.

The 2nd gear mod brings the ratio of the 2nd gear closer to that of the 1st gear and its a much smoother smoother transition between those gears. The 5th gear mod widens the gap between the 4th and 5th gear ratio. I did this mod because I wanted to be able to run 14T/49T sprockets for better offroad torque but at the same time be able to run this combination on the highway without the engine over-revving. The 2nd gear is available in the US or about $40 but the 5th gear can only be purchased in Europe. I got both gears off a complete used transmission I bought from a German seller on ebay for $175 shipped. Big big difference for anyone wanting to take on this mod but beware it does involve complete tearing your engine apart.

2nd 23421-MN9-010 available Honda USA ~40$
5th 23491-MW2-780 available Honda EU




@Virginian Notice the wider teeth on the 20 tooth counter shaft fifth gear is on the left, stock 21 tooth on the right. (props to flatfender for the pics on atvrider).

This chart will show how the ratios compare with other bikes.

New additions -- KLX250S, KTM690E


This list was getting too long, I've removed the 2-strokes, the trials bikes, and most of the bikes that were never sold as street legal. I have left the Honda XR650R on the list since it such a popular bike on this forum. You can find a more exhaustive list later in the thread.

The first number is the first gear ratio divided by the top gear ratio. The bigger the number, the wider the gear spread.

The number following the motorcycle name is what the actual overall low gear would be if gearing was raised until every motorcycle had the same ratio (5.05:1, or about what comes standard on a DR650 or KLR650) in high. Of course that caused all the first gear ratios to jump higher as well, so sorting by first gear, the lower the first gear ratio, the wider the overall gear spread.

Or put another way, if you replaced the sprockets on all these motorcycles so that they all had exactly the same gearing in high, this is how they would end up in first. The higher the number, the lower the gearing, and the wider the gear spread.

Hand guards

I have seen a post that most hand guards will not let the clutch and brake levers fit in side of them. This due to the levers being to long. Most folks are cutting the levers down.

I found these guards on ebay and they work really well and the levers fit inside the guards:

http://www.ebay.com/itm/360554981847...847%26_rdc%3D1

They are a pretty good item at a very good price. I put a set on my bike. Just thought I would pass it along for the help you folks have given me.

Excellent info, Sir!

I would have liked to get my hands on the taller fifth gear when I had my tranny apart. I'm fine with the stock first-second-third spacing. Ideally for me, a dual sport bike will have a wide range with a good low first, a good high top, and increasingly large gaps as the gears get higher. Of course we all agree that the XRL would greatly benefit from a sixth gear. Let's try 18/26 (0.69)

I have Acerbis handguards on mine that fit fine over the stock levers.

NX 5th gears are hard to get. If I could afford one I would buy it. You have to get it from overseas.

I think Barron might be able to hook you up if i recall correctly. Maybe PM him. I think he is over in Japan now.

I think he has a post or two about it in this thread. Probably in the 400 posts or so...

It would be perfect with the NX 2nd and 5th gears. Combine that with a built CW engine and some stock 15/45 gears for a 120mph beast.

I rode an 88 KX 500 for 2 years and did very well on it. I liked it. There were a couple of CR 500's in the circuit as well at that time.

I still haven't cracked my case yet (paid someone I trust to do it for me). I never really found a good option for swapping out the first gear with a 15T/45T sprocket setup to have the same ratio that I get from the stock gear with a 14T/48T sprocket ratio. It's just really nice to pop the front wheel up over a tall rock stair step. Maybe easier for you more competent riders but for a n00b like me, it's nice.

Thanks; I do remember being present for those discussions, or at least one set of them. But it's too late now, I already reassembled it after replacing the shifter shaft (with help from Steve) which broke one time when I went down on the trail. I couldn't really justify the expense at the time, anyway.

I started out with 14/48 as I got it from the P.O. I needed a higher top though the first three were fine. After some time, I tried the 15t front. I determined that made the first two or three too high, so I went back. Then bwalsh had a 50T rear he wanted to get rid of so I did the arithmetic and 15/50 is 90% of the stock 15/45 while 14/48 is 88% -- so they are close, but 15/50 is just a touch higher. That's what I'm running now. It's an okay compromise. If I could have the first three gears in 14/50 and fourth and fifth in 15/45, I'd do it. But as long as I'm wishing for the stars, I might as well wish for a six speed where the gears are spaced exponentially.

I've thought about that second gear alteration while riding, and I just don't see where and how I would personally benefit from making a smaller gap between first and second, and a larger gap between second and third. It seems just fine the way it is! :

If your bike is running well 14/45 should take you anywhere comfortably, at least for me it does
