The Schnitz Racing 705cc forged piston kit for the 1996-2010 KLR650. Will NOT fit 1995 and earlier cylinders. This piston is manufactured exclusively for Schnitz Racing. Designed and tested by Cary Aspy KLRCARY)
This kit has all the same features as the
685cc Kit but bigger.
Machine work is required. It includes, but is not limited to:
Removal of the old sleeve
- Clearancing of the inner cylinder wall for proper water movement to cool the new oversized sleeve (Dremel tool or hand grinder)
- Installation of new sleeve and O-rings
- Surfacing and boring of the cylinder
- Ring gap clearancing
Note: You will also need to clean the combustion surfaces of the head. To get maximum benefit of the increased displacement, you might consider cylinder head improvements.
This kit uses the same piston forging as the 685, but is 103.89mm, rather than 102.5mm. Actual displacement is 703.6cc. The piston is lightened further, so although larger, it is 4 grams lighter than the 685, and more than 80 grams lighter (average is 88grams) than stock. Like the 685, it will lower the level of vibration.
Due to the larger bore, a larger and stronger liner was required. The 705 kit liner is the strongest available for the KLR. This liner is custom made exclusively for Schnitz Racing. It is "cyro" treated to resist wear, and resist distortion at the base. It is larger in diameter and requires cylinder clearancing.
Schnitz Racing Recommends M-Tech Motorcycles for cylinder head porting, and cylinder boring/705 kit installation.
