It's his road bike its a Suzuki TLR and I think it's 998cc
The Suzuki TLR was produced from 1998-2002. The Hayabusa GSXR1300 bodywork was based on the TLR, looking like a muscle bike. However, the TL1000R is a 998cc big bore v-twin that puts out mountains of torque. Good for burnouts. It runs two pipes up to the tail, sounds thumpy and is definately a unique bike.
The engine was so good it is still used today by Cagiva, the SV1000 and some Suzuki motard version (DV1000?). But the engine has been tuned down over the years due to it being known as a "widow maker" (because stupid bike journos rode them ham-fisted, idiots) and power went down from 119rwhp to about 107rwhp by 2002. So the 1998 models are popular. My TLR puts out 125 genuine rwhp. TLRs are becoming a cult bike (like the Z900) and do not lose value as much as a GSXR. The 1998 TLR is worth $13K (an average TLR is around $11K) and the 2002 GSXR is worth $7,500. So you can see what bike I would keep.
There was a sticker I saw a while ago I should get for the TLR: "If you value your life like I value my bike, then don't **** with it!" LOL
