Africa Twin Parts

Many parts from the XRV750 (RD04) and XRV650 (RD03) Africa Twins are interchangeable with the Transalp. This page (Japanese) has a full history of the Africa Twin.

Fuel Tank

RD03 and RD04 fuel tanks (identical other than color scheme) fit the Transalp frame. According to this page, "the left AT petcock is the same as the petcock for a 1990 NT650 Honda Hawk" ($55 at BikeBandit.com).

Interference

The RD03/RD04 tank's petcocks may interfere with the Transalp engine.

Blackbert says that the right-hand petcock hits the clutch cable mount, and the left-hand petcock hits the coolant line. The right petcock is larger due to a drain plug, so swapping it fixes the clearance problem on the right-hand side, but leaves the left side unfixed.

Ladder106 replies that the Africa Twin tank requires a support, which is shown here.

Swingarm

The Africa Twin has an aluminum swingarm which is is longer than the steel Transalp swingarm. It can be fitting with relatively few problems. Notably, the drum brake stopper has to be ground to fit the Africa Twin swingarm (assuming an Africa Twin disc rear wheel hasn't been used as well), and a 124 link chain is needed.

Interchangeability

These parts diagrams indicate the compatibility of certain parts between the Transalp and the RD04 Africa Twin. Green indicates that the part numbers are the same, while red indicates that the parts differ. Yellow indicates that the part numbers are different, but the parts may be compatible nonetheless.

Suspension

Brakes

• XR650RR Super Motard mentions a Braking oversized rotor kit on an XR650L (despite the XR650RR title).
• See Transalp Brakes for information.

Exhaust

GSXR-1000

According to this thread (advrider.com), 2001 - 2004 GSXR1000 mufflers are a relatively easy add-on.

Not quite a direct bolt-on but close. I got two 15° bend stainless steel tubes from Burns Stainless and rotated them until I got the right angle. Then I made the flange to bolt on the muffler. I attached the muffler and then tacked the flange and the two sections in place. I'm not a welder so you won't see a close-up shot. I originally had a GSXR1000 muffler on because it was titanium. But when I put the bags and mounts on, the muffler was too big and in the way. So I swapped it out for a 750 or 600 unit, shorter but not titanium. Fortunately, it weighs the same due to the shorter length.

Electrical

Battery

YTX14AH-BS

According to this thread, the stock lead-acid battery, YB12A-B, can be replaced with a sealed lead-acid battery, YTX14AH-BS. The only modification necessary is to remove the battery insulator sleeve.

NT650

The same thread indicates that the sealed battery specified for a Hawk NT650V can be used on the Transalp, but it requires a 1/8" shim underneath and possible cutting of the battery sleeve.

Accessories

Luggage

Racks

• Happy Trails makes aluminum panniers and steel luggage racks. Their mounting kits are also usable with GIVI and Pelican cases.
• GIVI offers topcase adapters which replace the plate on the Transalp's rear carrier. They also produce crashbars.
  • The E200 Monorack plate is available for 1988-1996 applications (note that the E211 may also be listed, but is for 1997-1998 applications):
    • Midwest Cycle Supply
    • AZ Motorsports
    • Happy Trails

Crashbars

• The TN363 crash bars are available from AZ Motorsports and Happy Trail. Mounting these to a US-spec Transalp requires longer bolts across the front and minor trimming of the bike's plastic radiator guard.

Misc

• African Queens sells hard-core accessories.
