My original Honda AT bike.
Original suspension....
But now I decided to make some changes. Progressive front, Ohlins back and more ground clearance.

here is a short video:

Ah, I see. I have the 1988 version. Luckily I have an '88 anyway. The changes are probably miniscule anyway.

I've never had the pleasure of comparing the two side-by-side but most AT guys in europe regard the RD03 as the best model for offroad and the RD07 as the best road/touring variation.

This, of course, is subjective and any of these is still better than what they are offering today. But then, in my opinon, the 89-90 Transalp is better than what's offered today.

Better best

I like the placement of the air filter on the RD07.

I only had the pleasure to ride a 89 transalp and my RD07
so I guess that limits my opinoin.

I would take both! I will score a Transalp sooner or later.

I read in other forums that it is a good idea to go with a larger rear sprocket and corresponding larger front sprocket in order to save the chain slider.

Keep us posted with your impressions about handling after the conversion.

Do you know how much bigger sprocket? Like 46Teeth rear? 17 Front?
Is it possible to put like 17front and 47 rear?
Thank you for suggestion about that....

According to what I read 17 is OK. To keep the original ratio, that would correspond to about 48 in the back. But depending on the lift even 48 might not be enough.

Thanks! Translation / RR for this site will follow in the next weeks.

Lifting the AT:
I just did this last week with mine, performance test still pending. The shorter link in the rear is said to have a negative effect on the progression. Better put a longer shock (will come as soon as I got the money for that). the guys who realy lifter theis ATs (e.g. with 50mm WhitePower Extreme forks out of KTMs) usually use 17:52 to save the slider. On the RD03 you will in some cases have to cut 1mm of the teeth of the sprocket, otherwise it will touch the shift axle. There is also some material called "Murtfeld" which is said to be rather resistant. We will try this on Hardheaders RD03 during the summer. His bike is lifted approx. 8cm.

The best AT:
in my opinion is the RD07:
advantages to RD03/04: location of the air intake, +10HP, 140 rear tyre, stronger frame, better wind protection by the fairing, some kilos less than RD04
advantages to RD07a: two coils per cylinder, adjustable rear shock
... but that's just my opinion... ... and yes, I never rode an RD04 ...

Cheers, Andy

Can you just add an extension to the shock, like we do on the TA's?

I haven't seen an RD07 shock before, but this is what I've done...



It is a wheel nut, 1.5 x 14. The nut is about 25mm and the washer will add almost 2mm. Due to the link geometry the 27mm translates into a 4 to 6 inches of increase in height. Its cheap and I've been using it for almost a year, almost 2000 mi on it and no failure.

But I've noticed that this setup eats the slider fast. I changed the front sprocket to a 16T, but never thought about going bigger..hum

You can do the same XR-Fork longer shock thing like on the TA, but the AT is even heavier, so setting up the forks is not so easy and you trade two disks against just one, but you could keep the triples... And there is that nice kit around with extensions to the forks and a changed U-link, the mod will take you 2hours and give you 4cm...

Cheers, Andy
