ZXR400 review

Make:
Kawasaki
Model: ZXR 400
Year: 1991
Power: 62bhp (new) 58.8bhp (current)
Engine: 400cc 4cyl carb
Mileage: 26,000 miles


The ZXR400, we all know it’s not the fastest bike in the world, with a claimed 62bhp it wasn’t going to break any speed records as it left the factory, but that’s not the point. Owning and riding the 400 has been a goal of ours. After many hours behind the bars of this icon, the thing we’ve loved the most about this bike is its personality. It really comes out to play in the corners, with a solid chassis and stiff suspension it excels where bigger bikes are left struggling.

The high revving 400cc engine pulls when you reach 8-10,000rpm and screams all the way to 14,500. Anywhere less than 8krpm and quite frankly the bike is boring, and you are left wanting more, knowing it’s somewhere much higher up the rev range. When we use the bike for commuting, the gear box gets a good work out to keep the bike in some form of power band but when on track the high rev limit keeps you in peak power as you enter and exit the corners. On longer journeys it can become a little bit uncomfortable but the howl from the exhaust makes up for that.

When it comes to handling the little 400 isn’t without its flaws. On the bumpy, badly surfaced roads us UK riders are faced with, it can be a handful; we find ourselves really gripping the tank and not looking forward to the next bump in the road in case it lifts your arse out the saddle, again. Guide the 400 to some smooth roads and it wants you to turn later and lean further than you think is possible on such a small bike.

It gives you the confidence and precision you need to excel and progress at a pace that bigger bikes don’t expect. The brakes are confidence inspiring, there are no upgrades on this bike, and the standard 4-pot Tokicos with EBC pads are more than enough to stop what little weight there is. When on track you can find yourself out-braking some of the bigger bikes, much to their surprise.

Equipment is minimal on the 400, with not even a fuel light. We’ve found out a few times that filling up at 100 miles stops you running out of fuel in the pouring rain, but we didn’t buy this bike for MPG figures or boasting about how many miles we can get from a tank.
When it comes to reliability Kawasaki seem to have got it right, we’ve never had any problems with this 24 year old bike and with a very strong engine as shown on the dyno run (link)  we can see this bike going for years to come with some basic maintenance.

The ZXR400 isn’t a perfect machine, but show it some twisty lanes, or a short technical circuit and you will feel right at home perched upon this little pocket rocket.

Over all, we give the ZXR400 an 8.5/10 BirotarUK rating.
 









We would like to say a big thank you to Wil Collins for the photographs.

Suspension set up and power run


We planned to do a track day at Mallory Park on the BirotarUK sports bikes, but considering their age, we wanted to make sure that the bikes were prepared and correctly set up to ensure maximum safety and enjoyment. 

The SRAD was spoilt and received a full fluid flush, including engine oil, brake fluid and coolant. Due to the Gixxer’s terrible brakes it also received a full front brake overhaul including new standard discs, rebuilt front calipers with fresh seals, braided lines, upgraded the MC and HH Sintered pads. The difference is immediately noticeable and these upgrades have transformed the SRAD’s braking performance. 

 
The ZXR received an oil and filter change and some fine tuning and adjustments to the drive train. We felt the stock brakes and EBC pads would be up to the job on the track day. 

 
We searched for a motorcycle tuning company, and we came across Race Engineering by recommendation. We booked in the ZXR and SRAD’s suspension to be set up to the rider’s weight. 
 
We received great customer service form the team at Race Engineering. The technician was very knowledgeable and with ex-racing experience, we were confident in his ability. He was able to adjust the rebound, travel, dampening and sag on both bikes, and also advise us on the condition and health of the suspension itself.




 As you may have seen on Instagram, the bikes also had a power run each on Race Engineering’s Dyno. We were interested in seeing what kind of power the bikes were putting out. The old girls are not getting any younger, carburetors are now classed as ‘Stone Age’ technology and we have to admit, they have been ridden well over the years so it was great news for us to see the results. 


ZXR original spec: 400cc 4cyl carb
ZXR original power: 62 BHP
ZXR weight: 159KG
ZXR torque: 26ft-lb
ZXR power run results: 58.6 BHP
ZXR power to weight: 368.55 BHP



SRAD original spec: 600cc 4cyl carb
SRAD original power: 92 BHP 
SRAD weight: 174kg 
SRAD torque: 44ft-lb
SRAD power run results: 91.74 BHP
SRAD power to weight: 527.59 BHP




We would like to thank Race Engineering for taking care of us for the great customer service, expertise, advice, and a great cup of tea! We highly recommend them for any of your motorcycle tuning needs.

Herts Motorcycle Run


Last year, we attended the Herts Motocycle run, and it was brilliant! This year’s Herts Motorcycle Run takes place on Sunday 3rd May, starting at the Herts Police HQ in Welwyn Garden City following a 60 mile route and finishing at the Essex Motorcycle Show at North Weald Airfield – home of the Herts Air Ambulance. The event opens at 9am and the run leaves Police HQ at 10.30am. 

We will be attending again this year so we would like to invite you to meet at the Herts Police HQ in Welwyn Garden City and follow a 60 mile route along the A1 – A10 – A120 – M11 finishing at the Essex Motorcycle Show at North Weald Airfield, the home of the Herts Air Ambulance.

The show has some attractions including trade stands from various motorcycle dealers, stunt activities and the opportunity to try out the latest demo bikes. The Herts Air Ambulance helicopter will be present on the day subject to operations for people to view up close and meet the Crew.

Check out the route!


Please note that ‘L’ plate riders cannot participate due to the route being on motorways. Click here to find out more or to register. Be sure to let us know if you are going to join us!
