Comparison XJR1200('98)& XJR 1300 ('99)

This is a little comparison I wrote when the first 1300 model came out. I leave it here as I made it, but there're some notes I'd like to make. The difference between my late 1200 and my new 1300 is quite big. There is more torque, more overall power, and the front end (brakes included) is much better. The specs stayed the same of course.

 
Specs of the XJR 1200 & 1300 are not difficult to find. Therefore, I tried to make a comparison between the two models. At first sight, there's a lot of difference between the both, but while making this comparison I did not find any logical reason to turn in my 1200 for a 1300. But hey, take a look for yourself ! Yes, I know, very mucho numeros. Happily, there are some pictures at the bottom. OK ?

 

Part 1 : the engine

 

First things first. Let's take a look at all the things both models have in common.

Engine Type
 4-cylinder, 4 valves/cyl. aircooled with small oilcooler
Carbs
Mikuni 36 mm
Ignition
Digital Transistor
Electrics

And now the differences. How these affect performance will be shown furtheron.

78.1 kW (106Pk) by 8000 tr/min
The difference in fuel consumption : 7l/100km for the 1200, 7.38l/100 km for the 1300.

 

Part 2 : transmission

 

The only difference between both models is the chain drive : the 1300 model got the chain and sprockets from the YZF R1.

Part 3 : Suspension, frame & brakes

 

Now this is the part where things start to get a little more interesting. Both common and different aspects of both bikes are gathered here.

As you probably noticed, there's something more to say here. The slight differences in rear travel, rake and trail are certainly meant to improve a more sportive style of riding. As for the tyres : since the wheels have the same size, most 1200 models are set to 120/17, 180/17 as well. The 1300 model received the front brakes of the R1, which is probably the most innovating feature of the total "upgrade". In general, I'm not really impressed, the upgrade should have been more drastic for that. When the 1200 is driven by a good pilot, it will not be left behind by the 1300. The next table shows why.
