I think all the thunderbirds, legends, and adventurers have 7/8" bars. Some have more rise that others. I would think that the grips would interchange. Some model changes on the adverturer were wheel size, locking seat becoming non-locking later. Not all the sissy bars/rack are compatible even between the early/late adventurers. I am not sure if the turn signals changed.

MPG will depend on your right wrist. Bad MPG is fun! I have a friend that has an adventurer that gets 45 or better cruising down the road. The worst I have gotten on my Thunderbird is 35, but it was fun (can't seem to control that wrist). I think with lots of self control I would get 45 or better.

My Haynes shows both carbs and I think it was '98 that the change was made from Mikuni to Keihin, so you should be covered. Turn the page maybe? :-D

My personal opinion is that the Keihin is a better made carb since there's much less plastic and less slide/needle wear, but the Mikuni is supposed to be more flexible for tuning. I haven't worked on the Mikunis so I can't verify the last.

By 'aftermarket exhaust' do you mean the pipes from the engine or just the mufflers? If it's just the mufflers then there's no difference in peak power over the stock engine at about 60 RWHP.

If you've got a complete aftermarket exhaust system it's impossible to tell what the RWHP is without some dyno time.

I'd also point out that peak horsepower is a poor measure for determining the rideability of the bike. The real issue is how flat the torque curve is over the normal operating range.

There were some changes made in 1998 or 1999 so a lot of the 'trim' parts won't be the same as the earlier models.

Bike Bandit has a set of Triumph parts breakdowns online, so I'd recommend cross checking the part numbers for the various years you're looking at.

Bike Bandit uses their own part numbers, so don't take them to the dealers to order parts. :-D


Mileage should be somewhere around 40miles per US gallon. I've gotten as little as 32 and as much as 45. It depends on the accessories and how you ride. I got the 32 mpg with a big windshield on an 80 mph higway, and I've gotten 45+ on secondary roads at 50 mph and below.

I'm averaging around 42 mpg with mods, so you should do better with a stock bike.
