diff between the RS and GT?

My brother called and was thinking of trading his 2003 RS with 4700 miles on it for a low milage 2004 GT. BMW spec sheets show some differences, like different clutch, gear ratios,different frame.I thought the two were the same but for bolt on stuff? I'm thinking two different people wrote the spec sheets and made up their own numbers? Any imput?

Re: diff between the RS and GT?

Jim,

I can only speak of the 2004 models as I purchased mine in October of '04. One dealer had told me some of what you have heard/read - that the GT had a different rear end and gear ratios. He also pointed out the 40 or so pounds difference in weight (IIRC it was somewhere around there). He was trying to sell me an RS he had on the floor.

I investigated on my own by reading the brochures and at the BMW NA web site. I found that the rear end and gear ratios were identicle and that a lot of the weight difference was the system cases (since they were standard on the GT, BMW included them in the bike's weight).

I called the other dealer in town and he echoed my findings. Since they advertised heavily, I called Daytona BMW, OKC BMW, Chicago BMW and Max's BMW and they verified what I had found.

According to what I found the only differences in the 2004 RS and GT were (from font to back and to the best of my recollection):
  • Clear front and rear blinkers
  • Taller, electric windshield
  • Fairing wings - hand guards
  • Higher, non-adjustable handle bars with different grips
  • Round mirrors
  • Fairing wings - leg guards
  • Thicker, heated (on most) seat
  • Color matched system cases

Frame, engine, clutch transmission, rear end, exhaust, wheels, etc. were all identicle and interchangeable. For '04 the heated grips and cruise control were optional on the RS although most came with them. ALL GTs except for a very late shipment included heated grips, cruise ad heated seats as standard. There were also obviously different paint colors/schemes between the models.

Re: diff between the RS and GT?

Isn't the rear shock on the RS is firmer than the GT?

Re: diff between the RS and GT?

Shocks were essentially the same Showa's. The difference was you could get a sport/performance version (yellow spring) instead. I was told the difference was just the spring, and that it was progressive rather than a straight spring-rate. Could be the same source that said the gearing was different on the GT, though.

Re: diff between the RS and GT?

Your are correct! The standard rear shock shows up as the same p/n and the optional SPORT model is yellow and was only an RS option.

If you want to talk about options, it is my understanding that ALL GTs came with the 5.5" wide rear wheel while pre - '04 RS it was an option (although most '03s came with it).

Re: diff between the RS and GT?

hey thx guys! I was thinking since he would have to cough up 2500-4000 for the upgrade it wasnt worth it. He has the cases and heated grips. for a few bucks he could make his RS a GT. Maybe not get the electric windshield is all.All he would really gain is a different paint job.

Yep, and the reason for the really good shock and the 5.5" wheel is .......... BMW marketing kinda sucks. (I had to tell my dealer about the shock in 2003! BMW never sent out any promo on the options. I heard about the shock from our FCCTD.)

Re: diff between the RS and GT?

Before I bought my RS I took a GT for a good, long test spin. IMHO the GT was gutless compared to the RS. As I was riding the GT I just knew this was not the bike for me. It was more comfy that the RS but nowhere near as fun to ride. When I rode the RS, I fell in love with the power and smoothness. I don't know the specs for horsepower comparison but they are totally different beasts. What the RS lacks in comfort can be made up with bar backs (if you wanted) and aftermarket seats and pegs. What the GT lacks in power can't be made up for (except trading it for an RS).

You must of ridden one with issues as their motors, transmissions and electronics are IDENTICAL.....no detuning like the newer KGT vs KS. They both are rated at 130HP and have the same exact torque.

Keep in mind that they may feel a lot different as you have an '01 and they didn't make an '01 GT so it would have been the newer, more refined bike. I have ridden and ridden with many older and newer RS/GT models and they all seem to perform the same.

Perhaps that gt had issues. Dont know for sure either way. It just looked, felt and drove like an older bike than my 01 rs and had less power. Perhaps the owner wasn't telling ne everything.

Re: diff between the RS and GT?

The deal with rear end gears is the RS and GT have 2.75 ratio ring and pinion. The same year LT has a 2.62 ratio. The RS and GT have 6 spd boxes and the LT has a modified 6 spd, turned into a 5 spd with reverse.

Re: diff between the RS and GT?

The GT has adjustable rider foot pegs (additional holes drilled into the mounting plate), that allows two positions. The RS didn't have this feature (that I'm aware of)..although the fiche's show both as the same.

For those that may know, is the upper position on the GT the same as the RS, or the lower?

The fiche also shows a 60W alternator for both, yet I was under the assumption that the GT came with a higher output, perhaps 80-85W, since it was primarily marketed to be ridden "two up", and perhaps electrics being used by the passenger as well.

My RS (2003) has two sets of holes for the rider foot pegs.

My 2000RS has two sets, plus when I made my lowers I put two sets of holes, soooo, now I have four different positions.

The bikes are the same mechanically and frame and suspension wise. (there was a sport shock option)

The alternator is something like 800-850 watts for both.

The foot peg placement as well as the adjustments are the same. The foot pegs of the earlier K12RS were a bit higher but were changed with the facelift of 2002. The mounting brackets are the same.

Then there were difference in the seat (heated I think was an option as well at a bit thicker), windshield, fairing extensions upper and lower, painted luggage and rack (same as RS but non painted and optional), and bars (adjustable RS, not GT), cruise was standard GT, but optional RS at first.

Hope this helps.

Re: diff between the RS and GT?

RS had adjustable bars. GT came with the "Comfort" bars, no adjustment. But, the GT is an RS with some optional RS components as "standard" (including the comfort bars). There really isn't anything unique to the GT except for the marketing hype.

Re: diff between the RS and GT?

I came to the same conclusion on the differences , although my '97 RS is a bit on the 'naked' side missing parts they included on the later RS.

I think of both bikes like this: RS means Rally Sport - looks the mean speed bike it is with simple smooth bodywork but comes with elephant ears. The GT is well, "General Touring" with the comfort options.

In the car world I seem to remember GT was used to describe 1st stage 'General Tune' but there is no difference in engine specs on our bikes.

However, on important mechanics I treat them the same.

Re: diff between the RS and GT?

GT generally means Grant Tourer, and in the case of the K GT it certainly fits...

Glad to see the differences were negligible. But still want the newer 13GT. Guess it is the old in me coming out.
