I am on my 5th RD07 and have done MANY, MANY miles touring. During the ownership of these bikes I have tryed different sprocket size combos to allter the xrv´s gearing.

If anyone is intrested here are my 2 cents on getting the most out of the old girl. :D

To start of the OEM combo for the RD07 is a 16t front and a 45t rear. With that combo the bike just never seems to be in the right rpm range & motorway touring 110kph is torture compared to the bigger bmw´s.

I like the following combo:

Honda OEM rubber 17t front
JT sprockets 43t rear

This lets me cruize 100kph(60mph) @ 4000rpm(about 900rpm lower than oem) but it allso makes the bike much faster in the twisties. How is that possible you ask? :smile:

Well! when you make every gear !allot! longer you can stay in a lower gear and get faster pickup.

With 16t/45t I´m constantly shifting betwean 4th and 5th gear in the twisties. With 17t/43t I can run in 4th all day its so nice!

I allso love this combo for dirt roads, you can keep it in 2;nd and 3;rd without redlining it and get massive dirt ripping tourqe.

I feal NO difference in the speed and power of the bike & it´s sooooo smooth =)

I use this combo instead of 16t/40t since i can easly swap the 17t for a 16t if i want to do really slow technical offroad days and get nearly the oem settup....


Here are the parts I used if you want to try this amazing combo. AND REMEMBER ALLWAYS USE A HONDA OEM FRONT SPROCKET. I learned the hard way and had to change the output shaft =(

JT Rear Sprocket 43 Teeth for Africa Twin RD04/07/07A - Rugged Roads

OEM Honda Front Drive Sprocket (17T) for RD04/07/07A - Rugged Roads



If you are worried about loosing hooligan power with this setup you can check out my youtube. I have NO problem wheeling the africa with this setup.
It´s me in the clip on my #4 africa R.I.P. it was allso running 17t/43t. :thumbright:

How's the clearance on the front sprocket? Is this now not coming very close to the gear change lever?
Since i'm not a changing front sprocket kinda guy, isn't it better to stay with the 16 front and going 40 on the rear?

Nope! the 17t is perfect. If you go 16t 40t you will have to get a shorter chain. Maybe it will be ok fora a few miles if the chain is new but i am @ position 28 on the chain tentioner and the chain is new (with 17t,43t) you would probably be allmost all the way out with a 16/40...

The clearance is only a few mm´s. But after 10000km´s+ running 17t I have never sean any skratches on the gearshaft so it´s hair close but it wont touch it.

I have not tryed to put the front sprocket cover on with 17t maybe it wont fit? I will try to put the cover on this weakend and report back on that.

But changing to the 17/43 from the 16/45 that was on the bike when I bought it, MAN what a diference! It´s so smooth and it takes 0,56l/10km´s when riding HARD in the twisties runing in 4th gear and really pushing the bike. Allso did a few km´s dirt that day. On tour I would imagine it can go just under 0,5l/10km´s loaded but ridden "softer" The bike is in great condition and has an empty race can, new airfilter and allways run on 98 octance fuel.

I use a 17 tooth front off the vt500 with the standard 45 rear, D I D gold chain, did 18k with no adjustment (scottoiler) it knocks 500 rpm off at 80 mph, also it keeps the chain of the swing arm slipper.

interesting read......Im just looking into changing my set up from the standard 16/45 as I want to drop the rpm on the motorways, as I like to run at about 75mph:rolleyes:
