Introduction
Dear Krämer Customer,
We want to congratulate you on purchasing a Krämer GP2-890R series motorcycle.
The GP2-890R is the next level and the logical expansion of the Krämer Motorcycles
portfolio. Like the strong “EVO2-690” single, the two-cylinder model was developed
and built exclusively for use on the racetrack. With 130 hp and 100 Nm of torque
and a weight of only 309 lbs (140 kg), the GP2-890R stands for spectacular riding
dynamics without overwhelming the rider. Ideal for the most intense enjoyment on
the racetrack - and for hunting lap times!
This manual will serve as a guide to keeping your GP2-890R in race-ready shape.
If you have any questions concerning the operation or maintenance of your
motorcycle, please consult your Krämer dealer.

6Usage and Setup
Pre-Ride Inspection
• Check safety critical screws for
correct torque [See pg. 30]
• Check engine oil level - Oil level to be
centered between the “maximum” and
“minimum” indicators. [See pg. 8]
• Check coolant level - Coolant should
be visible at the bottom of the radiator ll
tting when the radiator cap is removed.
[See pg. 12]
• Check tire pressure in warm condition
(with tire warmers on)
Set to 2.3 bar (33 PSI) in the front tire and
1.65 bar (24 PSI) in the rear (Pirelli Superbike
Slick SC1 Tires). Tire temperature should be
75-85°C (167-185°F) while checking. Tire
warmers should always be used.
• Check fuel level - Recommended race fuel
amount is approximately 7.0 L (1.85 US gal)
per 20 minutes of riding time. Maximum fuel
capacity is 16 L (4.2 US gal).
• Check the chain tension [See pg. 9]
• Inspect suspension components (forks,
rear shock, linkages) for leaks, excessive
wear, or any looseness. [See pg. 20]
• Let the engine run up to 176°F (80°C),
during which the throttle should not be
turned.
Vehicle Break-in Procedure
Following the rst outing
(15-20 minutes):
• Screws should be checked for the correct
torque [See pg. 30] and general
condition.
• Bleed the front brakes [See pg. 18].
For the rst 100 km (62 miles)
• Do not exceed 70% of full brake pressure.
For the rst 200 km (124 miles)
• Do not exceed 7500 rpm.
After 2 hours of run time
• Change engine oil and lters.
Post-Race Service
After each race weekend or 5 hours ride
time, whichever comes rst:
• Remove and clean the fairing (except front
fender) [See pg. 14]
• Thoroughly clean the motorcycle (frame,
tank, swingarm, fenders, and rims)
• Check the visual condition and torque of
each screw [See pg. 30]
• Replace engine oil and oil lters
[See pg. 8]
• Bleed the front brake, rear brake, and the
clutch [See pg. 18]
• Perform chain maintenance
[See pg. 9]
Post-Crash Inspection
1. Remove the entire fairing (including the Intake Cover/Air
Filter Box). [See pg. 14]
2. Disassemble the air lter box and check for any
blemishes/dirt within the air lter box and air lter. [See
pg. 10]
3. Thoroughly clean the fairing and all exposed areas of the
motorcycle while checking for damage.
4. Replace any damaged parts with new ones.
5. Inspect Suspension. [See pg. 20]
Loosen the front axle pinch bolts and bottom triple
clamp bolts. Compress the front forks several times, to
insure functionality, before re-tightening every bolt to the
appropriate torque specications.
6. Clean and lubricate the chain. [See pg. 9]
7. Check the coolant level [See pg. 12]
8. Check the engine oil level [See pg. 8]
After crash the oil level may appear low, start engine, run
for 15 seconds, stop engine, and check level.
Typical crash damage to inspect:
- Front forks
- Handlebars
- Crash pads
- Crash pad frame mounting plates
- Rearset
- Shift & brake linkages
- Debris trapped between the linkages
CAUTION!
Danger of scalding
During motorcycle operation, the coolant
gets very hot and is under pressure.
– Do not open the radiator or other
cooling system components if the engine
or the cooling system are at operating
temperature.
– Allow the cooling system to cool down
before inspecting or servicing.

7
Usage and Setup
Raising the Motorcycle on Lift Stands

Motul MoCool coolant.
If the storage area will reach temperatures below 0°C
(32°F) drain the coolant completely.
5. Check the tire pressure.
6. Remove the battery from the motorcycle. Store in a
safe, warm area, 0°-30°C (32°-85°F), out of direct

Transporting / Loading
NOTE: Use wheel chock to stabilize front wheel.
Recommended Tie-Down Points
1. FRONT: Attach a soft-tie loop straps on the lower triple tree.
Lead the loop forward out the lower front fairing Aattaching
to the tie-down straps secured to a solid mounting point in the
transport vehicle.
• Use one on each side of the motorcycle.
• Tighten straps enough to tension the front forks partially, being
careful that the forks are not compressed completely.
2. REAR: Attach a tie-down strap around the rear wheel Band
tighten the strap rearward, preventing the motorcycle from rolling
forward.
CAUTION!
Don’t park the motorcycle in
direct sun.
The windshield can amplify the sun’s
radiant heat.
